Question

Find LN.

A. 38
B. 56
C. 58
D. 76

Answer 1

B. 56°

Explanation:

`20 \degree = (1)/(2) (96 \degree - \widehat{LN}) \\ \\ 2 * 20 \degree = (96 \degree - \widehat{LN}) \\ \\ 40 \degree = (96 \degree - \widehat{LN }) \\ \\ \widehat{ln} = 96 \degree - 40 \degree \\ \\ \huge \red{ \widehat{LN} = 56 \degree}`
