You are updating your garage and the only thing left to paint is your garage door. you
are only going to paint the side that faces the street. the garage door is 10 feet 8 inches
tall and 145 inches wide. you need to know the surface area of the side of the garage
door to determine how much paint to buy. the hardware store sells paint by how much
covers a square foot. what is the surface area you should report to the hardware store?
(hint: 1 square foot = 144 inches).

129 square foot

Step-by-step explanation:

Step 1: Convert height of the door to inches

Height of the door = 10 feet 8 inches

1 feet = 12 inches

10 feet = y inches

Cross Multiply

y = 120 inches

Height of door in inches = 120 + 8 =128 inches

Step 2: Find the surface area of one side of the door

Surface area = length x width

length = 128 inches

width = 145 inches

Surface area = 128 x 145

Surface area = 18560 inches

Step 3: Convert surface area from inches to square foot

Surface area = 18560 inches

1 square foot = 144 inches

         y           = 18560 inches

Cross multiply

144y = 18560

y = 18560/144

y = 128.89 rounded off to 129 square foot.

Therefore, you should report 129 square foot surface area to the hardware store.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

is there answer choices?
