In triangle stu, ut=5 and angles=21. find su to the nearest tenth

The answer is:

The second option,

We are working with a right triangle, it means that we can use the following trigonometric property:

Which applied to our problem, will be:

We are given:

m∠S, equal to 21°

The side TU (opposite) equal to 5 units.

So, substituting and calculating we have:

Hence, the answer is the second option

Have a nice day!

13.0

Step-by-step explanation:

The given angle is m<S=21.

The given side length UT=5 units.

This side length is opposite to the given angle.

Since we want to find SU, the adjacent side; we use the tangent ratio to obtain;

This implies that;

Therefore SU=13.025

The nearest tenth

SU=13.0
