Respuesta :

m<S = 36° so mRT = 36° x 2 = 72°

m<U = 1/2(mRS - mRT)
m<U = 1/2(118° -  72°)
m<U = 1/2 (46°)
m<U = 23°

Answer
A. 23° (first one)

The resulting angle of u is 23°.

It is required to find angle U.

What is circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

Given that:

The first step is determine ∠SRU,

180° - 118° = 62°

62°/2 = 31°

∠SRU = 31° + 90° = 121°

Then angle U from the triangle was determined using this formula,

∠U = 180° - ∠SRU - ∠S

= 180° - 121° - 36°

= 23°

Therefore, the resulting angle of u is 23°.
