Answer: If 1 and 2 are adjacent right angles, they are both 90º.
1 and 3 are vertical, which means they must be congruent, so 3 is also 90º
So: 90 + 90 - 90 = 90

Answer:
The slope is -2
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= (-1 -3)/(-1 - -3)
= ( -1-3)/(-1+3)
= -4/2
= -2
The slope is -2
