Answer:
12
Step-by-step explanation:
x - 12 / x + 36 = 0
Multiply both sides by x + 36
x - 12 = 0 ✖ (x + 36)
x - 12 = 0
Add 12 to both sides
x - 12 + 12 = 0 + 12
x = 12

Answer:
115°
Step-by-step explanation:
Knowing that the sum of all interior angles of any triangle is 180 degrees, we can find the measurement of the missing angle of the triangle. The calculation is 180 - 75 - 40 = 65. Then, notice that the blue angle and the missing angle are supplementary (linear; add up to 180 degrees). So we can find the blue angle's measurement by 180 - 65, so the answer is 115 degrees.
Answer: 
Step-by-step explanation:
By the exterior angle theorem,

So in order to compare, the measurements have to same units. So lets convert everything to feet.
George 2 yds = 6 ft Kelsey 68 inches = 5 ft 8"
Mariah 5 feet Brian 5 ft 10 "
George measured the tallest at 6'
