Answer:

16°

Step-by-step explanation:

A ladder leans against a building . The foot of the ladder is 2 feet from the building and reaches to a point 7 feet high on the building . The measured angle formed by the ladder and building can be computed below.

The illustration forms a right angle triangle. Two sides are given and we are told to find an angle

Distance form the foot of the ladder to the building = 2 feet

The ladder reaches a point in the building which is the height of the building the ladder head started from = 7 feet

Using SOHCAHTOA principle

tan ∅ = opposite /adjacent

where

opposite = 2 ft

adjacent = 7 ft

∅ = angle formed by the ladder and the building

tan ∅ = 2/7

∅ = tan⁻¹ 2/7

∅ =  15.9453959

∅ ≈ 16°

What is the perimeter of this shape? Use numbers only. *
olga55 [171]

Answer:

13

Step-by-step explanation:

The perimeter is all of the sides added together. Because this is a rectangle, the length and width are the same on both sides. They gave you the length and width, so just add them:

4 + 4 + 2.5 + 2.5 = 13.

So the perimeter of the shape is 13.

Liam uses 2 quarts of yellow paint and adds 3 1/4 Jars of blue paint.Evan uses 1/2 quarts of yellow paint and adds 5 1/2 of red
EleoNora [17]

Answer:

2 + (13/4)x = 1/2 + (11/2)y

Step-by-step explanation:

Let each jar of paint used by Liam be x

Let each jar of paint used by Evan be y.

Liam uses 2 quarts of yellow paints and adds 3 1/4 jars of blue paint. so we have

2 + 3 1/4x

= 2 + (13/4)x

Since Evan also uses 1/2 quarts of yellow paints and add 5 1/2 jar of red paint, we have

1/2 + 5 1/2y

= 1/2 + (11/2)y

Since they end up with the same volume of paint, we have

2 + (13/4)x = 1/2 + (11/2)y

The rule for subtracting integers can be used to subtract whole numbers. explain why.
a_sh-v [17]

The difference between whole numbers and integers is that whole numbers do not include negative numbers, whereas integers do. Therefore, the same rule used by integers can be used with whole numbers, so long as negative numbers are not used.
