Answer:
The first one is 141 degrees, the second one is 39 degrees, the third is 149 degrees, the fourth one is 98 degrees, the fifth one is 102 degrees, the sixth one is 50 degrees, the seventh one is 74 degrees, the eighth one is 83 degrees, the ninth one is 95 degrees, the tenth one is 162 degrees.
Step-by-step explanation:
Basically you can look at the lines and tell if they are the same degree or not and if they are not you subtract that number from 180 to get your degree. I've already done this worksheet before and got a 100%
First, separate the x's and the numbers:
+2x and -x
+3 and +5
Next, solve those sums:
+2x - x = 1x = x
+3 +5 = 8
Answer: A. x+ 8
Answer:
x = 63 degrees.
Step-by-step explanation:
So first, 2y - 30 = 68 degrees.
It is because of alternative interior angles.
2y - 30 = 68
2y = 98 Move the -30 to the other side
98/2 = 49 So, y = 49
So in a triangle, the 3 angles equal 180 degrees.
So you do 49 + 68 = 117 degrees. You do this, because the 2 angle not including x is 49 and 68
Then you subtract 117 from 180
180 - 117 = 63 degrees. You do this because the 3 angles of a triangle equal 180 degrees.
So x = 63 degrees
