Question

the measure of angle stw is 25°. the measure of angle wtv is 50°. the measure of angle stv is x°. find the value of x.

Explanation:

Step1: Identify angle - addition relationship

The measure of $\angle STV$ is the sum of the measures of $\angle STW$ and $\angle WTV$.

Step2: Set up the addition equation

$x=\angle STW+\angle WTV$.

Step3: Substitute the given angle - measures

Given $\angle STW = 25^{\circ}$ and $\angle WTV=50^{\circ}$, then $x = 25 + 50$.

Step4: Calculate the value of $x$

$x=75$.

Answer:

$75$
