Answer:
Answer are in the steps.
Explanation:
Most of the problems is parallelogram some angles are the same. 2 angles add up to 180° are known as supplementary angles also known as linear pair.
#1:
<1 = 148° , <2= 32° , <3 = 148° , <1 = 32° , <5 = 148° , <6 = 32° , <7 = 32°
#2: All of them are 90° because of linear lines that add up to 180° / parallelogram.
#3: If <1 = 130°, then <8 = 148°.
Because Parallelogram <1 and <8 transversal.
#4 If <5 = 53° , then <3 = 127°
Because <5 = <4 so <5 + <3 = 180°
#5 If <7 = 71° , then <3 = 109°
Because <7 + <3 = 180°
#6 If <4 = 65° , then <6 = 115°
Because <5 = <4 so <4 + <6 = 180°
