Answer:
B. 16 degrees
Step-by-step 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
According to PEMDAS, the parentheses would go first.
3+1 = 2
42/2=21
Hope this helps!
