J is your answer.

Slope is rise over run + your Y intercept.

Your y- intercept is the point in the graph in which the line passes through, the line passes through -2, so you know -2 is going to be your answer at the end. And slope is rise/run.

From one point to another, you rise 1 time , and run over 3 so you know your answer is

y = 1/3x - 2

hope this helps :)

Find the measure of angle C of a triangle ABC, if: d m∠A = 60°+α, m∠B = 60°−α

snow_lady [41]

Answer:

m∠C = 60°

Step-by-step explanation:

we know that sum of angles of a traingle is 18 degrees.

given

m∠A = 60°+α,

m∠B = 60°−α

we have to find m∠C

m∠A + m∠B + m∠C = 180

60°+α + 60° - α +m∠C = 180

+α and -α gets cancelled

120°+m∠C = 180

=> m∠C = 180° - 120° = 60°

Thus, measure of angle c is 60°.

I need help setting up my problem

The measure of angle A is 144.3 degrees and the angle to cut the molding is 54.3 degrees

<h3>How to solve for angle A?</h3>

Start by solving the acute part of angle A using the following sine function

sin(Ax) = (30 - 4)/32

Evaluate the quotient

sin(Ax) = 0.8125

Take the arc sin of both sides

Ax = 54.3

The measure of angle A is then calculated as:

A = 90 + Ax

This gives

A = 90 + 54.3

Evaluate

A = 144.3

Hence, the measure of angle A is 144.3 degrees

<h3>The angle to cut the molding</h3>

In (a), we have:

Ax = 54.3

This represents the angle where the molding would be cut

Hence, the angle to cut the molding is 54.3 degrees
