Which relationship in the triangle must be true?
2 answers:
Cosine stands for "complementary sine." The sine of an angle is the cosine of the complementary angle and vice versa. Complementary angles add to 90°.
Answer: sin(B) = cos(90 - B)
It's true for any angle, and it doesn't have much particularly to do with a triangle.
COS(B)=sin(180-B).
Because a triangle have a 180 degree angle

Work:
(5x - 22) + (4x + 4) = 90
9x - 18 = 90
9x = 108
x = 12
4(12) + 4 =
48 + 4 = 52
I worked them out on paper. I hope this helps. There’s a picture of the work.
29.98/24≈1.25
2.29-1.25= $1.04
