Answer:
116º
Explanation:
Okay so mRS and mUT is parallel, according to the symbols. So, we have to make an equation.
6x-28 = 4x+20
Now we just solve for x, lets subtract 20 on both sides, and the equation now becomes
6x - 48 = 4x
Now subtract 6x on both sides.
-48 = -2x
Now divide -2 on both sides to isolate x
24=x
Now we know x is equal to 24, so now we plug in 24 with x.
6(24) - 28 = 116.
So, mRS = 116º
Hope this helps!!
