Find the midpoint of the line segment with the given endpoints. R(-12, 8), S(6, 12) 1 (-3, 10) 2 (9, 2) 3 (10. -3) 4 (-9.2)

The answer is one.

Step-by-step explanation:

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
