Answer:

AB = 17 m, AC ≈ 19.2 m

Step-by-step explanation:

Drawing a line from A to the base creates a right triangle

with legs 8 and (25 - 10 ) = 15

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AB² = 15² + 8² = 225 + 64 = 289 ( take the square root of both sides )

AB = [tex]\sqrt{289}[/tex] = 17 m

------------------------------------

Using Pythagoras' identity i right triangle ABC

AC² = AB² + BC² = 17² + 9² = 289 + 81 = 370 ( take square root of both sides )

AC = [tex]\sqrt{370}[/tex] ≈ 19.2 m ( to 1 dec. place )

it seems that is wrong.sorry for that.

Answer:

y=25.5°

Step-by-step explanation:

because there's an isosceles triangle, 180-51 = 129

so 129/2 = 64.5, which is X

there is also a right angle so 90-64.5 = 25.5, which is y

Answer:

Answer:

A 3/5

Step-by-step explanation:Here’s one way to solve this problem.

Write sixty percent as a fraction having a denominator of one hundred.

Now, change sixty-hundredths to an equivalent fraction having a denominator of twenty, the total number of pitches.

Do this by dividing the numerator and the denominator by five.

Then, simplify the fraction twelve-twentieths by dividing the numerator and the denominator by four.

So, Lenora hit three-fifths of the pitches.

Answer:

Step-by-step explanation:

1). [tex]\frac{2}{3}n-\frac{3}{4}n+\frac{1}{6}n+2\frac{2}{9}n[/tex]

= [tex]\frac{2}{3}n-\frac{3}{4}n+\frac{1}{6}n+(2+\frac{2}{9})n[/tex]

= [tex](\frac{2}{3}-\frac{3}{4}+\frac{1}{6})n+(2+\frac{2}{9})n[/tex]

= [tex](\frac{8}{12}-\frac{9}{12}+\frac{2}{12})n+(2+\frac{2}{9})n[/tex]

= [tex]\frac{(8-9+2)}{12}n+(2+\frac{2}{9})n[/tex]

= [tex]\frac{1}{12}n+(2+\frac{2}{9})n[/tex]

= [tex](\frac{1}{12}+2+\frac{2}{9})n[/tex]

= [tex](\frac{3}{36}+\frac{72}{36}+\frac{8}{36})n[/tex]

= [tex]\frac{83}{36}n[/tex]

= [tex]2\frac{11}{36}n[/tex]

2). [tex]\frac{2}{5}g-\frac{1}{6}-g+\frac{3}{10}g-\frac{4}{5}[/tex]

= [tex](\frac{2}{5}-1+\frac{3}{10})g-(\frac{1}{6}+\frac{4}{5})[/tex]

= [tex](\frac{4}{10}-\frac{10}{10}+\frac{3}{10})g-(\frac{5}{30}+ \frac{24}{30})[/tex]

= [tex](\frac{4-10+3}{10})g-(\frac{5+24}{30})[/tex]

= [tex]\frac{-3}{10}g-\frac{29}{30}[/tex]

= [tex]-\frac{3}{10}g-\frac{29}{30}[/tex]

3). [tex]i+6i-\frac{3}{7}i+\frac{1}{3}h+\frac{1}{2}i-h+\frac{1}{4}h[/tex]

= [tex]7i-\frac{3}{7}i+\frac{1}{2}i+\frac{1}{3}h-h+\frac{1}{4}h[/tex]

= [tex](7-\frac{3}{7}+\frac{1}{2})i+(\frac{1}{3}-1+\frac{1}{4})h[/tex]

= [tex](\frac{98}{14} -\frac{6}{14}+\frac{7}{14})i+(\frac{4}{12}-\frac{12}{12}+\frac{3}{12})h[/tex]

= [tex](\frac{98-6+7}{14})i+(\frac{4-12+3}{12})h[/tex]

= [tex]\frac{99}{14}i-\frac{5}{12}h[/tex]

Answer:

b. 75°

Step-by-step explanation:

Draw a triangle. Write a person name and a point name (a letter) at each vertex: Sam A, Sonny B, and Sal C at the vertices.

Write the distances as AB = c = 153 ft; AC = b = 201 ft; BC = a = 175 ft.

We are looking for angle B.

Since we have a triangle with three side lengths and no angle measures, we use the Law of Cosines.

[tex] b^2 = a^2 + c^2 - 2ac \cos B [/tex]

[tex] 201^2 = 175^2 + 153^2 - 2(175)(153) \cos B [/tex]

[tex] 40401 = 30635 + 23409 - 53550 \cos B [/tex]

[tex] -53550 \cos B = -13643 [/tex]

[tex] \cos B = \dfrac{-13643}{-53550} [/tex]

[tex] \cos B = 0.254771242 [/tex]

[tex] B = \cos^{-1} 0.254771242 [/tex]

[tex] B = 75^\circ [/tex]

Answer: b. 75°

Answer:

[tex]x = 1[/tex] and [tex]y = -\frac{1}{3}[/tex]

Step-by-step explanation:

So we can equate the second equation in terms of y by dividing both sides by 12:

[tex]y = -\frac{1}{3}[/tex]

Let us substitute this into the first equation:

[tex]x + 3y = 0[/tex]  

then becomes  

[tex]x + 3(-\frac{1}{3} ) = 0[/tex]

which simplifies to

[tex]x - 1 = 0[/tex]

Finally solving for x gives us:

[tex]x = 1[/tex]

Therefore, [tex]x = 1[/tex] and [tex]y = -\frac{1}{3}[/tex]

Hope this helps!

Answer:

x=1, y=-1/3

Step-by-step explanation:

x-1=0

3 is not in the range.

A function's range is the whole set of potential values that it can have. When we insert an x value into the function, the range is the collection of values that results. Range refers to the y values.

Given a figure in which the function is not differentiable since the graph is broken at  (-2, 3) and (2, 4). Since at Y = 3 there is no point in the graph. therefore Y = 3 is not in the range of the function.
