#8 If anyone knows about This kind of question please help! :) I have included a picture from my study guide.

79 degrees

Step-by-step explanation:

A. Sum of interior angles is where you take two of the interior angles (ones inside the triangle) and add them to get the opposite angle outside the triangle, D in this case. So 41 + 38 = 79 degrees

B. a straight line has 180 degrees, you are given the angle next to D to be 101, so you find the difference between 180 and 101 to find D, so 180-101 = 79 degrees

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
