I will do 9 only. You can do 11.
Question 9
sin(60) = x/8
sin(60)(8) = x
4•sqrt{3} = x
x^2 + y^2 = 8^2
(4•sqrt{3})^2 + y^2 = 64
16(3) + y^2 = 64
48 + y^2 = 64
y^2 = 64 - 48
y^2 = 16
sqrt{y^2} = sqrt{16}
y = 4
Do 11 the same way.
Answer:
168 inches
Step-by-step explanation:
The amount needed is the perimeter.
Perimeter = 2(L+W)
L = 56
W = 28
Perimeter = 2(56+28) = 168inches
Answer:
Step-by-step explanation:
6*6*6 = 6³
6 ---> is the base
How many time the number is occurring will be the exponent
