Step-by-step explanation:
3(x+2)+2(x+2)
Distribute
3x+6 +2x+4
Combine like terms
5x +10
Answer:
13
Step-by-step explanation:
3 x 11 - 5 x 4
3 x 11 - 20
33 - 20
13
<span>3x + 2x = 90 {the two angles add up to 90°}
5x = 90 {combined like terms}
x = 18 {divided both sides by 5}
angle 1 = 3x
= 3(18) {substituted 18, in for x, into 3x}
</span><span>= 54° </span><span>angles add up to 90°
angle 1 = 3x
angle 2 = 2x
</span>
