Question

PLEASE HELP!! 50Points!! Im confused!!

Answer 1

C

Explanation:

Two angle are side to be compliment if there sum is 90°

<B + <A = 90°

<B = 90° - <A

<B = 90° - 40°

<B = 50°

Two angle are side to be compliment if there sum is 180°

<B + <C = 180°

<C = 180° - <B

<C = 180° - 50°

<C = 130°

m<B + m<C = 50° + 130° = 180°

Answer 2

1:

`\\ \sf\longmapsto <A+<B=90`

`\\ \sf\longmapsto <B=90-40`

`\\ \sf\longmapsto <B=50`

• Now

`\\ \sf\longmapsto <B+<C=180`

`\\ \sf\longmapsto <C=180-50`

`\\ \sf\longmapsto <C=130`

So

`\\ \sf\longmapsto <B+<C=130+50=180`
