40% percent times 70 is want I believe
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
24-8 would be? right 16 so the 16+2=18 the times 10 would be 180/4 would be.45
If you are asking about the percent then it would be 83.33%
