Answer:
b = 9 ft
Step-by-step explanation:
Pythagorean Theorem:
a^2 + b ^2 = c^2
Given:
a = 12
b = ?
c = 15
Plug in values:
12^2 + b^2 = 12^2
Solve for b^2:
b^2 = 15^2 - 12^2
b^2 = 225 - 144
b^2 = 81
Take square root of both sides to find b:
sqrt(b^2) = sqrt(81)
b = 9
Hope this helps! :)
Absolute value is always positive, unless there is a negative sign outside of the lines

Step-by-step explanation:
if x=4, then -4x4+4y=16
so, -16+4y=16
so, 4y=16+16=32
so, y=32/4
so, y=8
and x=4
