Question

In triangle Jkl, l = 880 inches, Angle j=63° and Angle k=11°. Find the length of j , to the nearest

inch.

Answer 1

j=816 inch

Explanation:

J^+K^+L^=180° (sum of int. angles of triangle)

L^+11+63=180

L^=106°

j/sinJ=l/sinL

j/sin63=880/sin106

j*sin106/sin106=880*sin63/sin106

j=815.6

j=816 inch
