Question

Find the value of x given angle srt=angle str m angle srt=20 and m angle stu=4x

Answer 1

Congruent angles have equal measure.

The value of x for $\mathbf{\angle SRT = \angle STR}$ is 5

The given parameters are:

$\mathbf{\angle SRT = \angle STR}$

$\mathbf{\angle SRT = 20}$

$\mathbf{\angle STR = 4x}$

$\mathbf{\angle SRT = \angle STR}$ means that:

$\mathbf{20 = 4x}$

Divide both sides by 4

$\mathbf{5 = x}$

Rewrite as:

$\mathbf{x = 5}$

Hence, the value of x for $\mathbf{\angle SRT = \angle STR}$ is 5
