∠a and ∠b are vertical angles with m∠a=x and m∠b=3x−60 . what is m∠a ?

m∠A=30°

Step-by-step explanation:

we know that

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

Vertical angles always are congruent

In this problem

m∠A=m∠B ----> by vertical angles

we have

m∠A=x

m∠B=3x-60

substitute

Solve for x

therefore

m∠A=30°

false

step-by-step explanation:

whenever we assume a point on a plane then according to geometry it will definitely have 2 dimensions and if it assumed in space then it will have 3 dimensions.
