Answer:
The other angle is 190-7x.
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
Let A be the third angle.
A + (3x-20) + (4x+10) = 180
A = 180 - (3x - 20) - (4x + 10) = 190 - 7x
You simplify it by solving it which means it's 4x4 which equals 16 so the answer is 16
1/4 = 5/20
2/5 = 8/20
8/20 + 5/20 = 13/20 has been spent
