Alvin's age + Elga's age = 84
2R + R = 84
3 R = 84
3/ 3 R = 84/ 3
R = 28
Elga's age is 28
113.04 is the volume
V = pi x r^2 x h
3.14 x 2^2 x 9 = 113.04
It might be d but i’m not sure
Answer:
x=12
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
5x+8x+2x =180
Combine like terms
15x = 180
Divide by 15 on each side
15x/15 =180/15
x=12
I think it's along the y-axis.....
