Answer:

c) 60°

Step-by-step explanation:

We solve this question using trigonometric function of Cosine.

cos θ = Adjacent/Hypotenuse

θ = ???

Adjacent = Base of the ladder is on the ground = 2.5 feet

Hypotenuse = Length of the ladder = 5 feet

cos θ = 2.5/5

θ = arc cos (2.5/5)

θ = 60°

Therefore, the measure of the angle created by the ladder and the ground is 60°

3 numbers are in arithmetic progression their sum is15 and their product is 80 determine the 3 numbers
Mashcka [7]

Answer:

2, 5, 8

Step-by-step explanation:

For starters, let us assume that the numbers are x-d, x, and x+d.

Where d is the common difference between terms.

This mean that we can say, from the question

x-d + x + x+d = 15

3x = 15,

x = 5,

This means that the terms are 5, 5-d and 5+d.

On the other hand,

(5-d) * 5 * (5+d) = 80

(5-d) * (5+d) = 80/5

(5-d) * (5+d) = 16

25 - d² = 16

d² = 9

d = + or - 3.

Finally, the three numbers will be 2, 5, and 8. On the flipside, their sum and product are 15 and 80.
