Hello! I am happy to help you.
Here, x=36.
2*36=72*2=144+36=180. A triangle's measure equals 180.
Hope this helps!
Yeah, base is ten and the two sides are 5...
Answer:

3)The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value. y = 2 - 3(-5/7) becomes 2 + 15/7, which is 29/7.
Is there a problem equation?
