Answer 1

the answer is

32 degrees

Explanation:

Answer 2

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
