What is the value of r? enter your answer in the box. round your final answer to the nearest whole number. r = units a right triangle has a horizontal leg labeled 12 with its opposite angle labeled 67.4 degrees. the hypotenuse is labeled r.

13 units

Step-by-step explanation:

Given: A right triangle has a horizontal leg =12 units

The opposite angle to the horizontal leg = 67.4 degrees

In trigonometry, the value of sine of an angle (x) in a right triangle is given by:-

Since, the hypotenuse is labeled as r.

Then , we have

Hence, the value of r = 13 units.
