Question

Answer the question correctly​

Answer 1

Step-by-step explanation:

(perpendicular)AB = 24

perpendicular)AB = 24(base)BC = 7

by using Pythagoras theorem we can find hypotenuse(AC)

AC^2 = AB^2 + BC^2

AC^2 = (24)^2 + (7)^2

AC^2 = 576 + 49

AC^2 = 625

AC = √625

AC = 25

∆ABC RIGHT ANGLED AT B

sinA = perpendicular/hypotenuse

sinA = BC/AC

sinA = 7/25

cosA = base/hypotenuse

cosA = AB/AC

cosA = 24/25

sinC = perpendicular/hypotenuse

sinC = AB/AC

sinC = 24/25

cosC = base/hypotenuse

cosC = 7/25
