The image is missing, so i have attached it.

Answer:

area he will cover with paper = 196 in²

Step-by-step explanation:

From the image, we see that the base of the face= 8 inches while the height is 14 inches.

We know area of triangle is;

A = (1/2) x base x height

Thus;

A = (1/2) x 8 x 14 = 55 in²

This is area of one side face.

Thus area of 3 side faces = 56 x 3 = 168 in²

Thus, total area covered is;

Area of side faces + area of base = 168 + 28 = 196 in²

A 25-foot ladder leans against a house. The bottom of the ladder is 7 feet from the house.

Liono4ka [1.6K]

It makes a 74 degree angle.

The sides of the triangle that are given are the side adjacent to the angle the ladder makes with the ground and the hypotenuse of the triangle.

adjacent/hypotenuse is the ratio for cosine:

cos x = 7/25

To solve this, we will take the inverse cosine:

x = cos⁻¹(7/25) = 73.7 = 74
