Let
x-----> the measure of the angle formed by the wooden fence and grass
we know that
in a right triangle
tan x=opposite side angle x/adjacent side angle x
opposite side angle x=13 ft
adjacent side angle x=21 ft
so
tan x=13/21x=arc tan (13/21)-----> x=31.76°------> x=32°
the answer is
32 degrees
7+5=12 so it can be one of these 8+4=12, 9+3=12, 10+2=12, and 11+1=12.
∠A+∠B=∠ACD
So, ∠A=93-31=62°
I think it mean that, right?
All triangles equal 180 degrees
92 + 50 = 142
180 - 142 = 38
Angle A equals 38 degrees
Angle 92 and Angle d Are supplementary which means that both angles added together equals 180
180-92 = 88
Angle d = 88 degrees
9 because it's the gcf(greatest common factor)
