Answer:

x = 5

Step-by-step explanation:

The sum of interior angles in a triangle is 180°

91° + 10x - 4° + 8x + 3° = 180° add the like terms

90° + 18x = 180°

18x = 180° - 90

18x = 90° divide both sides by 18

x = 5

Pythagorean
nata0808 [166]

Answer:

5√3 ft

Step-by-step explanation:

If the ladder is 10ft tall, then that represents the hypotenuse. If the foot of our ladder is 5ft away from the wall, that is a side length that we know. Using the Pythagorean Theorem, a²+b²=c², where a and b are side lengths of a right triangle, and c is the hypotenuse, we can solve for the missing side length:

a²+b²=c²

(5)²+b²=(10)²

25+b²=100

b²=75

b=√75

b=5√3

So the ladder will reach a height of 5√3 ft.
