Answer:
c = 45 and e = 30
Explanation:
Since we know that A = 45, B = 90, we can calculate C knowing that the total angle of a triangle is 180, so you do 180-45-90 = 45
Finding the angle C helps us find F by subtracting 45 from 180, since a straight line is 180 degrees, which is 135.
We know that E = 15, and what was said earlier about how the toal angle is 180 in a triangle, we can subtract 15 and 135 from 180, which is 30.
Hope that answers your question
