Step-by-step explanation:

1.5 ft

Step-by-step explanation:

Use the Pythagorean theorem and rearrange it to find the third length.

3.6^2 + x^2 = 3.9^2

3.9^2 - 3.6^2 = x^2

15.21 - 12.96 = 2.25

sqrt 2.25 = 1.5

x = 1.5

answer: your gay

step-by-step explanation:

you dont know math

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
