Question

What is the value of X in degrees?
A.13.8
B.16
C.20
D.24

Answer 1

B. 16 degrees

Explanation:

Because all of the angles in a triangle add up to 180 degrees, you can set up an equation for this problem:

2x - 10 + 4x + 46 + 3x = 180

Start by consolidating everything by adding like terms.

9x + 36 = 180

Then subtract 36 from both sides.

9x = 144

Then divide both sides by 9 to get your x.

x = 16
