Question

ANSWER. IT. PLEASE. ​

Answer 1

Answer:

a = 65°  b=115°  c=25°

Step-by-step explanation:

The interior angles of a triangle always add up to 180°.

You can figure out B easily because angles A and B equal 180°. First figure out angle A. Add 55° and 60° and then subtract it from 180. You can find angle C after you figure angle B the same way you figured out angle A. I hope this all makes sense. Feel free to send me a message if you need more help.

Answer 2

Answer: a = 65°, b = 115° and c = 25°

Step-by-step explanation:

We know that sum of a triangle is 180°. So we can get a value for a.  A = 180° -(60°+55°) which is 65°.

We know that angle a and b are supplementary so 180°-65° = 115°.

Then, for the final step, we know that sum of a triangle is 180°, so we know that c = 180°-(115°+40°) which is 25°

Hope this helps;)
