Answer:
3
Step-by-step explanation:
the perpendicular slope is the negative reciprocal.
-1 divided by -1/3 = 3
2 42/100 turn it to a fraction
Angle a is directly opposite from a 40 degree angle, so a=40. Then we can find b since the sum of the angles of all triangles is 180 and there is a right angle in there along with angle a:


Last, to find c we just notice that it is supplementary with an angle of measure 65, so:


So our angles are a=40, b=50, c=115.
