Question

Can someone please answer these questions for me?

Answer 1

Answer:

5. 106°

6. 16.6°

Explanation:

5. 53 plus 53 equals 106

the exterior angle equals 106 degrees

6. 8x+5 = 40 + 5x + 15

8x+5= 55+5x

subtract 5 from both sides

8x=50+5x

subtract 5x from both sides to try to isolate x to one side

3x=50

divide 3 from both sides

x= 16.6

Answer 2

Answer:

106° , 155°

Explanation:

5.

53° + 53° = 106°

6.

40 + (5x + 15) = 8x - 5

5x - 8x = - 5 - 15 - 40

- 3x = - 60

- x = - 60/3

- x = - 20

x = 20

40 + (5 * 20 + 15) = 8 * 20 - 5

40 + 115 = 160 - 5

155 = 155°
