Answer:
[tex]\Huge\boxed{74}[/tex]
Step-by-step explanation:
Hello There!
First things first, we need to find the value of x
If you didn't know the measures of supplementary angles add up to equal 180 so we can use this equation to solve for x
180 = 2x + 3x - 5
step 1 combine like terms
2x + 3x = 5x
now we have
180 = 5x - 5 step 2 add 5 to each side
-5 + 5 cancels out
180 + 5 = 185
now we have 185 = 5x
step 3 divide each side by 5
5x/5=x
185/5=37
we're left with x = 37
Now we want to plug in 37 into x for angle A
angle a = 2(37)
2*37=74
so we can conclude that angle A = 74
