remember, when you multiply two expressions, you need to multiply every term of the first expression with every term of the second expression, and then add all partial results (by considering the individual signs, of course).
If m∠4 = 90°, find the m∠5 and m∠3.
Answer:
∠5 = 90°
∠3 =90
Step-by-step explanation:
∠4 + ∠5 = 180 {Linear pair}
90 +∠5 = 180
∠5 = 180 - 90
∠5 = 90°
∠3 = ∠4 {Verically opposite angles}
∠3 = 90°

this is for my geometry final please help me pass
Step-by-step explanation:
cos(x) = 5/13
the relation is
sin²(x) + cos²(x) = 1
so,
sin²(x) + (5/13)² = 1
sin²(x) + 25/169 = 169/169
sin²(x) = 144/169
sin(x) = 12/13

Two people meet in the conference room on the fourth floor of a building. On departure, one person travels West
24 feet, South 18 feet, and Down 18 feet. The other person travels North 24 feet, East 12 feet, and Up 18 feet.
How far apart are the two people? Round to the nearest tenth.
Answer:
36*(5)^0.5
Step-by-step explanation:
distance on horizontal 36 feet
distance on vertical 78 feet
so distance between them = (36^2+78^2)^0.5 = 36*(5)^0.5
The two people are 66 feet apart from each other.
How to elaborate the problem ?
The 1st person travels 24 feet west, 18 feet south and 18 feet down.
The location of 1st person is (-24, -18, -18) , the negative sign is to convert all in same direction.
The 2nd person travels 12 feet east, 24 feet north and 12 feet up.
The location of 2nd person is (12, 24, 18)
How to find the distance between them ?The distance between (-24, -18, -18) & (12, 24, 18 = [tex]\sqrt{(-24-12)^{2}+(-18-24)^{2}+(-18-18)^{2} }[/tex] feet
= [tex]\sqrt{(-36)^{2}+(-42)^{2}+(-36)^{2} }[/tex]) feet
= 66 feet

what is the quotient of 1,224 divided by 9
Answer:
136Step-by-step explanation:
Simply divide the numbers, the result is the quotient
1224/9 = 136The quotient of the given expression when 1,224 divided by 9 is 136.
The quotient is defined as the number obtained on dividing a number with some number.
The number left after the division is called as the remainder.
Example: When 37 is divided by 5, the quotient is 5 and the remainder is 2.
The quotient of the following expression can be calculated as:
When 1224 is divided by 9, it gets divisible in 136 times completely, leaving no remainder.
So, it can be said that 136 is the quotient when 1,224 divided by 9.

Find the length of BC.
Explain how you got it, please!

Answer:
BC = 30.73
Here,
[tex]\sf \frac{AB}{BQ} = \frac{CD}{DQ}[/tex]
so first solve for QD
[tex]\sf \hookrightarrow \frac{32}{15} = \frac{19.2}{DQ}[/tex]
[tex]\sf \hookrightarrow 32(DQ)} =19.2(15)[/tex]
[tex]\sf \hookrightarrow 32(DQ)} =288[/tex]
[tex]\sf \hookrightarrow DQ =9[/tex]
Hence, QD = 9Now! using Pythagoras theorem,
CD² + BD² = BC²19.2² + (9+15)² = BC²BC = √368.64+576BC = 30.73499634BC = 30.73 ( rounded to nearest hundredth )Answer:
BC = 30.7 units (nearest tenth)
Step-by-step explanation:
As ∠AQR = ∠CQR then ∠AQB = ∠CQD
This means that ΔABQ ~ ΔCDQ
Therefore, the side lengths of two similar triangles are proportional.
[tex]\begin{aligned} \sf \dfrac{AB}{CD} & =\sf \dfrac{BQ}{QD}\\\sf \implies \dfrac{32}{19.2} & =\sf \dfrac{15.0}{QD}\\\sf \implies QD & = \sf 9 \end{aligned}[/tex]
Pythagoras' Theorem: [tex]\sf a^2+b^2=c^2[/tex]
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
a = BD = BQ + QD = 15 + 9 = 24b = CD = 19.2c = BCSubstituting values into the formula:
[tex]\begin{aligned}\sf 24^2+19.2^2 & = \sf BC^2\\\sf BC^2 & = \sf 944.64\\\sf BC & = \sf \pm\sqrt{944.64}\\\sf BC & = \sf 30.7 \ (nearest \ tenth)\end{aligned}[/tex]

Nate surveyed 90 students at his school about their favorite class. Based on the graph, how many of the 630 students in the school would be expected to say their favorite class is Reading or Math?
Using proportions, it is found that 420 students in the school would be expected to say their favorite class is Reading or Math.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, out of 90 students, 20 + 40 = 60 students prefer reading or math. How many do out of 630? Thus, the rule of three is given by:
60 prefer reading of math - 90 students.
n prefer reading of math - 630 students.
Applying cross multiplication:
90n = 630 x 60
n = 630 x 60/90
n = 7 x 60
n = 420
420 students in the school would be expected to say their favorite class is Reading or Math.

What is the equation of the circle pictured?
Explain your reasoning.
Answer:
(x+2)^2 + (y-4)^2 = 4^2
Step-by-step explanation:
A circle is x^2 + y^2 = 1 , where r = 1
The radius of that circle looks to appear to be r = 4.
x^2 + y^2 = 4^2
Transition that circle origin from (0,0) to (-2,4)
The origin is (-2,4) which mean h = -2 left and k = 4 up.
(x-h)^2 + (y-k)^2 = 4^2
(x-(-2))^2 + (y-4)^2 =4^2
