Given right triangle pqr which represents the value of sin(p)?

answer: the correct answer is option 3.

step-by-step explanation:

we are given a triangle, right-angled at r. we need to find the value of trigonometric function,

to write the sine-function, we use the equation:

side opposite to vertex p is rq and hypotenuse is the side opposite to right angle which is pq.

the value of is:

hence, the correct answer is option 3.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
