Answer:
d) sin(45°) = 13/
Step-by-step explanation:
Trig ratios:
sin(x) = O/H
cos(x) = A/H
tan(x) = O/A
where x is the angle, O = opposite side to angle, A = adjacent side to angle, and H = hypotenuse
From inspection, we have been given the measure of the side OPPOSITE to the angle and the measure of the HYPOTENUSE.
angle = 45°
opposite side = 13
hypotenuse =
Therefore, substitute these values into the sine trig ratio:
⇒ sin(x) = O/H
⇒ sin(45°) = 13/
