the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.
x+(2x+15)+the measure of angle Q should equal 180.
Since everything is addition, the parenthesis can be removed.
x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.

A= B + 3(4-C)
Answers
Answer:
A = 11
Step-by-step explanation:
A = B + 3(4 - C) ← substitute B = 5 , C = 2 into the equation
A = 5 + 3(4 - 2) = 5 + 3(2) = 5 + 6 = 11
4-2=2 and 2 times 3 = 6 6 + 5 = 11
