8. David needs to order fabric for a triangular sail with the dimensions shown below. x feet
16 feet
12 feet
If the base of the sail is 12 feet long and the height is 16 feet, what is the value of x?
a. 28
b. 112
c. 20
d. 28

answer is x<

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
