If ∠c and ∠d are vertical angles and m ∠ c = x + 5 and m ∠ d = –2x + 80, what is m ∠ c?

m∠C=30°

Step-by-step explanation:

we know that

Vertical Angles are the angles opposite each other when two lines cross. They are always equal

so

m∠C=m∠D

substitute the given values

Solve for x

Find the measure of angle C

m∠C=(x+5)°

substitute the value of x

m∠C=(25+5)=30°

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
