I think it’s 5. I’m not sure
Answer:
5(30 + 2)
Step-by-step explanation:
5(32)=160
5(30+2)=160
The rest equal different numbers
Answer:
Angle A = 50
Step-by-step explanation:
We know the 3 angles of a triangle add to 180
A + B+C = 180
2x-10 + 70 + x+30 = 180
Combine like terms
3x+90 = 180
Subtract 90 from each side
3x+90-90=180-90
3x = 90
Divide by 3
3x/3 = 90/3
x = 30
We want to find angle A
Angle A = 2x-10
= 2(30) -10
= 60-10
= 50
