∠A and ∠B are vertical angles with m∠A=x and m∠B=3x−60 . What is m∠A ?

kow [346]

Answer:

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

$3x-60=x$

Solve for x

$3x-x=60$

$2x=60$

$x=30$

therefore

m∠A=30°
