Answer 1

All of the angles in a triangle add up to 180. From there you make an equation which would give you the value of y.

We know that the bottom line is straight, so it equals 180*. QRS is supplementary to the R* angle, which is 144*. All supplementary angles add up to 180, so 180-144 would give us 36* for the Value of QRS.

Now we know QRS=36* and the sum of all the angles is 180, we can write the equation
6y + 36 =180
y= 24

Now you plug the y in ... giving you the value of angle S to be 24* and angle Q to be 120.

QRS = 36*
Q= 120

Answer 2

See explanation

Explanation:

So, the angle for QRS is the interior angle of R. The exterior angle outside of angle R is for the equation you are going to use. Because angle R is on a straight line, the interior angle of R plus the exterior angle of R will equal 180 degrees. From there you should be able to calculate the rest of the angles, I believe you should be able to calculate y first.
