B= 97°

C = 43°

A = 40°

Step-by-step explanation:

Ok so we want to find the angle measurement for A.

We already have the angle measurement for B and C.

The interior angle of a triangles should ALL add up to 180°.

A + B + C = 180°

A = ???

B = 97°

C = 43°

So

A + 97° + 43° = 180°

A + 140° = 180°

    -140°   -140°

A = 40°

So the angle measurement for A will be 40°

Check:

A + B + C = 180°

40° + 97° + 43° = 180°

137° + 43° = 180°

180° = 180°

Correct

Did this help?

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

y=x+9
