Question

angle a and angle b are vertical angles with measue of angle a=x and measure of angle b=5x-80​

Answer 1

Answer:

we know that

Vertical Angles are the angles opposite each other when two lines cross. They are always congruent to one another

in this problem

∠A and ​ ∠B ​ are vertical angles

so

∠A=∠B ​

we have

∠A=

∠B=

equate angle A and angle B

solve for x

therefore

the answer is

the measure of angle A is
