Answer:
18/38 or 9/19
Step-by-step explanation:
18 squares are red
18 squares are black
2 squares have 0 or 00
This is a right triangle, the measure of angle A is 90 degrees.
First thing to do I guess is finding B and C.
tan^-1 (7/12) = 30 degrees
tan^-1 (12/7) = 60 degrees
60 + 30 = 90
180 - 90 = 90. Therefore angle A = 90 degrees
