2) A ladder is leaning against the side of a house.
The base of the ladder is 8 feet away from the
wall, and the top of the ladder reaches a point on
the house that is 15 feet above the ground. The
ladder is x feet long.

What is the value of x?

A.7ft B.13ft C.17 ft D.23 ft

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
