What is linear pair?Linear pairs of angles are created when two lines cross at a single point. Angles are said to as linear if they are contiguous to one another following the junction of two lines. If two angles are adjacent and their measurements add up to 180°, they are supplementary. As a result, a pair of linear angles always sums to 180°.
In a linear pair, the total of the two angles is always 180 degrees.Angles that are next to one another are called linear pairs, however not all adjacent angles are linear pairs.A common vertex and common arm are shared by a pair of linear angles.Given:
<1 = 5x-15
<2 = 90
<3 = 2x
Now, using Linear pair
5x - 15 + 90 + 2x= 180
7x + 75 = 180
7x = 180-75
7x= 105
x= 105/7
x= 15
Hence, the value of x is 15.

Answer:
x=113º
Step-by-step explanation:
67 + x is a linear pair
they would be supplementary if they were next to each other
the 67º represents the acute angle directly next to xº
so
x+67= 180º
subtract 67º from both sides
180-67=113
x=113º

write the integers that are closest to the the number in the middle to complete the statement.
___<square root of 73<___
Answer:
see explanation
Step-by-step explanation:
Consider perfect squares on either side of 73, that is
64 < 73 < 81 , then
[tex]\sqrt{64}[/tex] < [tex]\sqrt{73}[/tex] < [tex]\sqrt{81}[/tex] , that is
8 < [tex]\sqrt{73}[/tex] < 9
Answer:
8<square root of 73<1
i think this are the integers that are closest to the number in the middle.
Find three consecutive EVEN integers such that the sum of the smallest number and twice the middle number is 20 more than the largest number.
Answer:
10, 12 and 14Step-by-step explanation:
x - an integer
2x - an even integer (the first and the smaller of the three)
Consecutive integers increase always by 2
2x+2 - next even integer consecutive to 2x (the middle one)
2x+2+2=2x+4 - the last consecutive even integer (the largest)
2•(2x+2) - twice the middle number
2x+2•(2x+2) - the sum of the smallest number and twice the middle one
2x+4+20 - 20 more than the largest number
2x+2•(2x+2) = 2x+4+20
2x + 4x + 4 = 2x + 24
-2x -2x
4x + 4 = 24
÷2 ÷2
2x + 2 = 12 ← the middle number
-2 -2
2x = 10 ← the smallest number
2x+4 = 10 + 4 = 14
Check: 10+2•12=34; 14+20=34
3n - 7m for n = 5 amd m = 4
Answer:
-13
Step-by-step explanation:
first you will subsitute 5 for n in the equation to get 3(5)-7m
next you will subsitute 4 for m in the equation to get 3(5)-7(4)
then solve: 3x5= 15
7x4= 28
15-28= -13

graph a line with a slope of -5 that contains the point (-3, -4)
Answer:
y = -5x-19
Step-by-step explanation:
Use the point-slope formula to plug in the x1 and y1 and the slope -5 to get the equation y = -5x-19.
Formula: y-y1 = m(x-x1)
m = slope
x1 = x-value
y1 = y-value
Answer:
y=-5x-15
Step-by-step explanation:
starts off in point-slope form:
y+4=-5(x+3)
distribute the 5:
y+4=-5x-15
subtract 4 from each side:
y=-5x-20
^that answer is in slope intercept form.
