Kurt leans a 20-ft long ladder against the side of his house. The ladder reaches to a height of 18.9 feet up the side of the house. What is the angle of elevation of the ladder to the nearest tenth of a degree?

70.9°

Step-by-step explanation:

Hypotenuse = 20

Leg = 18.9

We will need to use Sin to find the angle since the given leg is opposite of the angle of elevation.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

the answer should be a. snail
