Answer:

x=-8 y=-2

Step-by-step explanation:

substitute x for 2y-4

7(2y-4)+5y=-66

factor

14y-28+5y=-66

add 28 on both sides

14y+5y=-38

19y=-38

divide by 19 on both sides

y=-(38/19)

y=-2

Plug -2 into the first equation for y

x=2(-2)-4

x=-4-4

x=-8

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
