Answer:

270°

Step-by-step explanation:

∠ PQR = 90° ( angle in a semicircle )

PRST is a cyclic quadrilateral

The opposite angles in a cyclic quadrilateral are supplementary, sum to 180°

Then

∠ PRS + ∠ PTS = 180°

∠ PQR + ∠ PRS + ∠ PTS = 90° + 180° = 270°

M= 0 passes through the point (-1,3)
Len [333]

Answer:

y = 3

Step-by-step explanation:

I will assume you want to put this in slope intercept form.

We need to solve for b in y = mx + b since we are given a point and the slope.

y = 0x + b

y = b

3 = b

y = 3

Note that since the slope is 0, there will be nothing to represent m.

Best of Luck!
