During one hour of television there are two shows on. That would be the ratio 1:2. We need to find 3:?. Since 1×3 is 3, we multiply the second number by 3 as well. 2×3 is 6. So the ratio would be 3:6.
The sum of the internal angles in a simple pentagon is 540°.
105 + 135 + 92 + 87 = 419
540 - 419 = 121
The angle is 121
