what is the measure of angle a in the triangle?

enter your answer in the box

30

Step-by-step explanation:

The sum of all the angles in a triangle is always, always, 180 degrees.

Just add the angles, then solve for x.

(2x - 10) + (x + 30) + 70 = 180

3x + 20 + 70 = 180

3x + 90 = 180

3x = 90

x = 30

50 degrees.

Step-by-step explanation:

(2x - 10) + (x + 30) + 70 = 180...combine like terms

3x + 90 = 180

3x = 180 - 90

3x = 90

x = 90/3

x = 30

m < A = 2x - 10 = 2(30) - 10 = 60 - 10 = 50

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
