Quick comprehension check
“In a right triangle, the length of the adjacent side is 8 and the length of the hypotenuse is 10. Calculate the cosine of the angle opposite the side of length 8. Show all work. In another right triangle, the length of the opposite side is 5 and the length of the hypotenuse is 13. Calculate the sine of the angle opposite the side of length 5. Show all work.”
