Answer: 12.1 ft
Step-by-step explanation:
A ramp represents a right-angled triangle so Pythagorean formula can be used to find the diagonal length which will also be the hypotenuse.
c² = a² + b²
Where:
c = hypotenuse
a = base
b = Height
c² = 11² + 5²
c² = 121 + 25
c² = 146
c = √146
c = 12.1 ft
The answer is the 3rd one
Answer:
sine 52 degrees = height / 78
height = 78 * sine 52
height = 78 * 0.78801
height = 61.46478 feet
rounded to nearest tenth 61.5 feet
Step-by-step explanation:
Answer:
31 feet
Step-by-step explanation:
Given: The length of ladder, leaned against wall= 32 foot
The base of ladder is 8 feet away from wall
Adjacent= 8 feet and Hypotenuse= 32 foot
we need to find height of wall till the ladder reach (Opposite).
We will use Pythagorean theorem; 
⇒
⇒
subtracting both side by 64
⇒ 
⇒
≅ 31 ft
∴ 31 ft high up the wall.
Answer:
She makes $4.66
Step-by-step explanation:
In this problem we are required to calculate the profit she makes from each bracelet
Given data
Selling price for a bracelet =$9
Cost price for a bracelet = $4.35
Profit= selling price- cost price
Profit = 9-4.35= $4.66
