Answer:
m∠2 = 103°
Step-by-step explanation:
Since ∠1 and ∠2 are supplementary angles, together they equal 180. So, you would just subtract 180-77 and get 103. To check if you are correct just add ∠1 and ∠2 ( 77+103) and you'll get 180.
Answer:
Step-by-step explanation:
The sum of two supplementary angles sum up to 180°
Hence <1+<2 = 180°
Given
<1 = 77
Substitute and get <2
<1+<2 = 180
77+<2 = 180
<2 =180-77
<2 = 103°
Hence the measure of <2 is 103°
