Question

what is ( mangle srt )?

write your answer as an integer or decimal.
( mangle srt = square^circ )

Explanation:

Step1: Identify equal radii

$RS = RT$ (radii of the same circle)

Step2: Classify triangle $\triangle SRT$

$\triangle SRT$ is isosceles, so $\angle RST = \angle RTS = 38^\circ$

Step3: Calculate $\angle SRT$

Use angle sum of triangle: $\angle SRT = 180^\circ - 2\times38^\circ$
$\angle SRT = 180^\circ - 76^\circ = 104^\circ$

Answer:

$104$
