Question

Can someone help me out? i’m not sure what the answers would be for these 5, thanks.

Answer 1

Answer:

<6 and 4 are supplementary angles. Supplementary angles add up to 180. therefore <6 and <4=180--->m<6=65---->180-65=115--->   m<4-115

2. 115°

By using vertical angles theorem we see that angles opposite to each other like 5 and 8 are congruent.

Therefore m<8 = m<5

3. 122

<3 and <6 are congruent by the alternate interior angles theorem which states that interior angles that are opposite one another such as 6 and 3 are congruent.

4. 73°

<4 and <7 are supplementary since the <4 is equal to the <8 and the <8 is supplementary to 7.

180-107=73

5. 73°
