Question 684169: If the measures of three angles in a triangle are (2x+15)º,(10x – 20)º, and (3x + 2)º, then find the value of 15x – 3. Answer by unlockmath(1688) (Show Source):
You can put this solution on YOUR website! Hello,
Let's determine what x equals by setting up:
(2x+15)º+(10x – 20)º+ (3x + 2)º = 180
Combine like terms:
15x-3=180
Add 3 and divide by 15 to get:
x=12.2 degrees
Now we can figure out 15x-3:
180 degrees
Make sense?
