Answer:
118•
Step-by-step explanation:
The interior side lengths are:
90
180-34
180-x
180-x
The sum of these are 360º
90 + 180-34 + 180-x + 180-x = 360
-2x = -236
x = 118º
Answer:
16.
Step-by-step explanation:
The highest common factor between the two is 16.
So, you need to do the same operation to each side.
Start out by subtracting 3 from each side
1/4 (20x+8) = -3
Then, multiply both sides by 4
40x+8 = -12
Then, subtract 8 from each side
40x = -20
divide both sides by 40 and you get
x=-1/2
Hope this helped!
