In right triangle hjk, angle j is a right angle and tan angle h = 1. which statement about triangle hjk must be true? a. sin angle h =1/2. b. sin angle h = 1. c. sin angle h = cos angle h. d. sin angle h = 1 divided by cos angle h

Step-by-step explanation:

Givens

is a right triangle.

We this information, we can deduct that the opposite leg to is JK, and the adjacent leg to is JH. So, if  , this means that both legs are equal, because to result the tangent in 1, both legs have to be equal

Also, we can deduct that the angle is equal to 45°, because when the tangent is equal to one unit, that means the triangle is symmetric, which means that its angles are 45°.

So, with knowing the measure of , we can find the rest of trigonometric reasons

Basically, this means that both reasons are equal

Therefore, the right answer is C.
