Both add up to 90 degrees as they are complimentary angles:
5x + 3x + 2 = 90
8x + 2 = 90
8x + 2(-2) = 90(-2)
8x = 88
8x/8 = 88/8
x = 11

Answer:
I think number 2 is the answer, but 4 could be the answer.
Answer: x=−9/4
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(x+14)+1=5
Step 1: Simplify both sides of the equation.
−2(x+14)+1=5(−2)(x)+(−2)(14)+1=5(Distribute)−2x+
