right angle triangle, adjacent = 4330mm, hypothenus @ 15 degrees, hypothenus length please.

Question

 I need to know the length of th hypothenus of a right angled triangle when the adjacent is 4330mm, and the hypothnus is at 15 degrees.

Answer 1

We know that

CosA = adjacent side/hypotenuse

hypotenuse = adjacent side/CosA

A = 15, adjacent side = 4330mm

hypotenuse = 4330/Cos15

= 4330/0.9659

= 4510.41mm

Comments

hypotenuse = 4330/cos(15) = 4330/0.9659 = 4482.86mm.
