Question

find the value of x.
a. 8
b. 36
c. 10
d. 12

Explanation:

Step1: Set up the equation

The sum of the angles \(50^{\circ}\) and \(5x^{\circ}\) is \(110^{\circ}\). So, \(50 + 5x=110\).

Step2: Solve for \(x\)

Subtract \(50\) from both sides: \(5x=110 - 50\), which simplifies to \(5x = 60\). Then divide both sides by \(5\): \(x=\frac{60}{5}=12\).

Answer:

D. 12
