Angle 1 and 2 are supplementary angles, meaning they must add up to 180°. You can tell this because they share a side and together, their other side forms a straight line (and straight lines are 180<span>°).
Knowing this, you can make an equation to solve for x: Angle 1 + Angle 2 = 180</span><span>° </span>10x + 4 + 5x – 4 = 180° 15x = 180° x = 12°
Knowing x = 12°, you can plug the value of x into the equation for angle 2 to find its measurement: <span>Angle 2 = 5x – 4 </span>Angle 2 = 5(12°) - 4 Angle 2 = 56°
If there were 6 cats, there would be 4 dogs. Since there is double that amount of cats, then we just double the amount of dogs from 4 to 8, our final answer.
