Answer:

x = 25, The angles of the triangle are 60*, 45*, and 75*.

Step-by-step explanation:

The sum of the angle measure is 180 so we can form this equation:

60 + (x + 20) + 3x = 180

Now isolate the variable to find x.

(x + 20) + 3x = 120

4x + 20 = 120

4x = 100

x = 25

Now solve for the angles of the triangle.

3(25) = 75

(25 + 20) = 45

Answer:

m∠CAB = 40°

Step-by-step explanation:

DAC = 99

DAB = 59

B is inside DAC, and so is DAB. So CAB must add to 59 to get to 99, nothing over that because it's inside DAC.

So 99 - 59 = 40

CAB must be 40°

That's all I can say for now. Hope this helps and a thank won't hurt! :)

Point-Slope Form<br> *See photo*

Answer:

y = 3x - 5

Step-by-step explanation:

We know that the equation 'y = 3x + ?' intersects the point (1, -2). This means that when x = 1, y = -2 in out equation above. To solve this just plug in the x and y values to get '?'.

$y = 3x + ?\\-2 = 3(1) + ?\\-5 = ?$

Now that we know '?' is -5, we write it back into slope intercept form, so our final answer is y = 3x - 5
