In triangle ABC, if angle A + angle B = 5 angle C, find angle C

30

Step-by-step explanation:

A + B = 5C

A + B + C = 180

since A + B is 5C we can rewrite with 5C

5C + C = 180

6C = 180

c = 30

)

3+11

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

∠cbe and ∠deb are same-side interior angles.
