This problem involves using the Pythagorean Theorem which is a^2+b^2=c^2
We already have the values of a and c, but b is unknown. So we plug in: 11^2+b^2=20^2
121+b^2=400
b^2=279
b=sqrt(279)
b=16.7
So the answer is about 16.7 ft

Answer:
$0.50
Step-by-step explanation:
.
8x+140=180
8x=40
x=5°
Sum of angles in a straight line=180°
-4
t2 - t1
-13 - (-9)
-13 + 9
= -4
