Question

I think angle BAC is 40° and CAS is 130° but pls tell me your answers.​

Answer 1

Answer:

your answers are correct

BAC is 40° and CAS is 130°

Step-by-step explanation:

in triangle ABC

<BAS=90

<ABC=<BAS=90 (opposite interior angles are equal)

therefore <CAB=180-(<ACB+<ABC) (angle sum property)

<CAB=40

<BAC=40

<CAS=<BAC+<BAS

<CAS=40+90

<CAS=130
