Question

What is x equal to ? Link down below.

Answer 1

50

Explanation:

Because of supplementary angles that line has to equal to 180

180-75 = 105

so 105 = (2x + 5)

you can subtract 5 from each side and get

100 = (2x)

then divide each side by 2 and you get

x = 50

you can check it by doing (2 x 50 + 5)

2 x 50 = 100 + 5 = 105 + 75 = 180

Answer 2

x = 50

Explanation:

Those two angles are on the same straight line. That means

1. They are supplementary.
2. They add up to 180 degrees

Solution

2x + 5 + 75 = 180 Given

2x + 80 = 180 Combine like terms on the left

2x + 80 - 80 = 180 - 80 Subtract 80 from both sides

2x = 100 Divide by 2 on both sides

2x/2 = 100/2

x = 50 Answer
