Question

Find the measure of ∠3. a. 118 b. 62 c. 31

Answer 1

Answer:

angle 3 = 31

because there are three angles in a triangle if we add 118+31=149 and it has the capacity for a third angle.

Answer 2

$answer = 62 \\ solution \\ \: let \: < 3 \: be \: x \\ x + 118 = 180(sum \: of \: angle \: in \: triangle) \\ or \: x = 180 - 118 \\ x = 62 \\ hope \: it \: helps \\ good \: luck \: on \: your \: assignment$
