Can someone explain this? A ladder 12.2 meters long can be so placed that it will reach a window 10.1 meters above the ground on one
side of the street. If a person tips it back without moving its foot, it will reach a window 6.4 meters above the
ground on the other side of the street. Find the width of the street.

understand that i don't know the answers

will someone answer his question

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.

answer: the answer is b. i think hope i got it correct
