Question

What 5 degrees is equal to

Answer 1

<5 = 105

Explanation:

<4 = 105

Because l and m are parallel, <4 and <7 are supplementary (they = 180) That means you can find <7

<4 + <7 = 180

105 + <7 = 180 Subtract 105 from both sides

<7 = 180 - 105 Combine the right side

<7 = 75

<5 and <7 are also supplementary because they have their bases on line m

<5 + <7 = 180

<5 + 75 = 180 Subtract 75 from both sides

<5 = 180 - 75

<5 = 105

You should understand that all 8 angles are either 75 degrees (<2,3,6,7) or 105 degrees (<1,<4,<5,<8)
