Answer:
Step-by-step explanation:
X + 3 = 2x +5
-x -5 = -x - 5
x = -2
40° and 50°
complementary angles sum to 90°
let x be the angle then it's complement is x + 10
sum = x + x + 10 = 90
2x + 10 = 90
subtract 10 from both sides
2x = 90 - 10 = 80
divide both sides by 2
x = = 40
thus the angle is 40° and it's complement is 40 + 10 = 50°
Answer:
c = 72
Step-by-step explanation:
multiply both sides of the equation by 8 to eliminate the fraction
c = 8 × 9 = 72
note that = 9
The bed of the truck is a rectangle, 4-ft wide and 8-ft long.
The diagonal of the rectangle is
√ (4² + 8²)
= √ (16 + 64)
= √ (80)
= 8.9442... feet
8.9442... feet = 8 feett 11.33 inches
Rounded to the nearest inch: 8 ft 11 in .
