The answer is 26.53 m, since you’d have to use trig to find the length of the ground, then calculate the top of the house using tan, then add 20m to the length of the top of the house, which is 6.53 m.

I need help with geometry
olchik [2.2K]

Answer:

m<1=?

m<2=4x-20..........(1)

m<4=3x-11.............(2)

Step-by-step explanation:

we have

  • m<2=m<4(corresponding angle of parrelelogram are equal)
  • 4x-20=3x-11
  • 4x-3x=20-11
  • x=9

again.we have

<1+<2=180(co-interior angle)

<1=180-<2=180-(4×9-20)=180-16=164
