In a triangle, the three interior angles always add to 180°
m∠R + m∠S + m∠<span>T = 180
</span><span>(2x+10) + (2x+25) + (x-5) = 180
</span>2x+10 + 2x+25 + x-5 = 180
5x + 30 = 180
5x = 150
x = 30

because if you put in 60 for 20 you would have to multiply 3 to get 60 so you do 3x13 and it would equal 39
Answer:
-a (14 +a) =0
Step-by-step explanation:
-14a-a^2=0
Factor out -a
-a (14 +a) =0
Using the zero product property
-a =0 14+a =0
a =0 a = -14
