Answer: Correct Answer is 4th option , 28

Step-by-step explanation:

We can find the measure of the angle using the tangent.

We know, tangent of an angle = Perpendicular/Base, corresponding to that angle.

So, Tan of angle T = RG / RT

or, Tan of angle T = 8/15

or, angle T = tan inverese of 8/15

or, angle T = 28.07

So, angle T rounded to nearest degree = 28

Hope this helps.

Thank you.
