Answer:
Step-by-step explanation:
A, B and C must be real numbers, and A and B are not both zero (which would cause division by zero in the calculation of the slope).
25% can be made in to 100% by multiplying it by 4.
Therefore, we can find the answer by multiplying 80 by 4.
80 * 4 = 320
There are always 180° in a triangle, so to work out the missing angle, you add up the angles you have and do 180 - that answer.
So it would be:
79 + 37 = 116
180 - 116 = 64.
y = 64 :)
