Question

Find the measure of

Answer 1

Explanation:

let the missing side be x

a^2+b^2=c^2

6^2+12^2=x^2

36+144=x^2

180=x^2

`\sqrt{180` =x

6
`\sqrt{5` =x

for angle C

take angle C as reference angle

using tan rule

tan C=opposite/adjacent

tan C=6/12

tan C=0.5

C=
`tan^(-1)`0.5

C=26.6 degree
