You need to solve for a/b:
10/7 * a = 7/10 * b
Divide both sides by b:
10/7 * a/b = 7/10
Multiply both sides by 7/10:
a/b = 7/10 * 7/10
a/b = 49/100
So the ratio of a to b is 49 to 100

10a/7 = 7b/10
a/b = 7*7/(10/10) = 49/100
10/(7*a) = 7/(10*b)
100/49 = a/b

enable's call the different angles 7x and 10x. all of us comprehend that the angles in a triangle upload as much as one hundred eighty ranges. seventy 8 + 7x + 10x = one hundred eighty. remedy for x. Multiply by utilising 7 to get one attitude and multiply x by utilising 10 to get the different attitude.
