∠a and ∠b are vertical angles with m∠a=x and m∠b=3x−60 . what is m∠a ? enter your answer in the box.

we know that

Vertical angles are congruent angles opposite each other where two lines cross

so

in this problem

m∠A=m∠B

so

substitute the values

therefore

the answer is

The measure of angle A is

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
