Question

LE and LF are supplementary. If m LE =
(9x - 38)° and m LF = (2x + 42)°, find m LF

Answer 1

74 degrees

Explanation:

Supplementary angles are two angles whose sum is 180 degrees.

<LE + <LF = 180 degrees

9x-38+2x+42=180

11x + 4 = 180

11x = 180-4

x = 176/11

x = 16

<LF = 2(16)+42

<LF = 74 degrees
