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
Answer:
a = 16
Step-by-step explanation:
24:8 is the ratio
simplify into 3:8
6 ÷ 3 = 2
multiply the ratio by 2 to get a=16
