Can you help me find the measure of each angle? Diagram attached

never [62]

<u>Answer:</u>

5x = 100°

4x = 80°

<u>Step-by-step explanation:</u>

We are given a diagram with a straight line AC being intersected by another line BD and we are to find the two mentioned angles.

We know that the two angles (5x° and 4x°) are supplementary so their sum would be equal to 180°.

So we can write it as:

$5x+4x=180$

$9x=180$

$x=\frac{180}{90}$

$x=20$

Finding the measure of both the angles:

$5x = 5(20) =$ 100°

$4x = 4(20) =$ 80°

Express it in slope-intercept form.

Answer:y=3/2x-3

Step-by-step explanation: the slope of the graph is (y2-y1)/(x2-x1)

If we take points (0,-3) (2,0) the slope would be (0--3)/(2-0) = 3/2

And the y-intercept of the slope is -3
