Answer:

<1 = 130

<2 = 50

Step-by-step explanation:

<1 = 130 since it is an alternate interior angle and alternate interior angles are equal when the lines are parallel ( a is parallel to b)

<1 + <2 = 180 since the form a straight line

130+ <2 = 180

<2 = 180-130

<2 = 50

Answer:

Solutions given:

m<1=130°[alternate angle are equal]

A carpenter is constructing a staircase in a house. The distance from the first floor to the basement is 9.2 feet. The staircase will be 13.3 feet long. What angle do the stairs make with the basement floor?

Answers

Answer:

43.77°

Step-by-step explanation:

The height, h = first floor to basement = 9.2 feets

Length of staircase = hypotenus = 13.3 feets

Angle stacase makes with basement floor, θ

Using trigonometry :

Sinθ = opposite / hypotenus

Opposite = height = 9.2 feets

Sinθ = 9.2 / 13.3

Sinθ = 0.6917293

θ = sin^-1(0.6917293)

θ = 43.77°
