The surface area of the cone will be : 169.65 so it would be answer A as 54 x pi = 169.646003
Answer:
Step-by-step explanation:
Let the measurement of the smaller angle = x
Larger angle = 4x + 10
x + (4x + 10) = 90 {complementry}
5x + 10 = 90
5x = 90 -10
5x = 80
x = 80/5
x = 16
Smaller angle = 16
Larger angle = 4*16 + 10 = 64+10 = 74
Using the Pythagorean theorem:
12^2 + x^2 = 15^2
144 + x^2 = 225
x^2 = 225 - 144
x^2 = 81
x = sqrt(81)
x = 9
Answer:
Well -7>-7.5
Step-by-step explanation:
Negative numbers are that the Humber that is closest to 0 is the greatest. Like in -7 and -7.5, the -7 is closer to 0 so its greater.
