PLEASE HELP!

Mathematics
1 answer:
Tanya [424]3 years ago
6 0

Answer:

R = 10.39^\circ

Step-by-step explanation:

Since you have the lengths of all the sides, you can use sine, cosine, or tangent to find the answer. Let's use the tangent ratio.

For angle C, AB is the opposite leg, and BC is the adjacent leg.

\tan C = \dfrac{opp}{adj}

\tan C = \dfrac{22}{120}

C = \tan^{-1} \dfrac{22}{120}

C = 10.39^\circ

Answer:

∠ U = 60°

Step-by-step explanation:

The tangent- tangent angle U is half the difference of its intercepted arcs

minor arc VT = 120° , then

major arc VT = 360° - 120° = 240°

Then

∠ U = \frac{1}{2} (240 - 120)° = \frac{1}{2} × 120° = 60°
