Question

calculating angle measures. what is the value of y? y = (10y + 6)° (8y - 6)° 5 6 10

Explanation:

Step1: Set up equation

Since $\angle{JKM}$ and $\angle{MKL}$ are supplementary (linear - pair of angles), $(10y + 6)+(8y - 6)=180$.

Step2: Simplify the left - hand side

$10y+6 + 8y-6=18y$. So, $18y = 180$.

Step3: Solve for y

Divide both sides by 18: $y=\frac{180}{18}=10$.

Answer:

10
