Let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why?

Point C cannot be inside ∠AOB

Step-by-step explanation:

we know that

If point C is in the interior of ∠AOB

then

m∠AOB=m∠AOC+m∠COB -----> by addition theorem postulate

Verify

Substitute the values

Remember that

1 degree is equal to 60 minutes

so

therefore

Point C cannot be inside ∠AOB

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.
