Look at the triangle:

A right angle triangle is shown with hypotenuse equal to 13 centimeters. An acute angle of the triangle is labeled as x degrees. The side adjacent to the acute angle has length 5 centimeters, and the side opposite to the acute angle has length 12 centimeters.

What is the value of sin x°?

The sine of an angle is equal to the opposite over hypotenuse

sin(angle) = opposite/hypotenuse

sin(x) = 12/13

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).
