Ihope some one knows how to answer this.

in this figure, m\angle3=x+18, m\angle4=x+15,\& m\angle5=4x+3.m∠3=x+18,m∠4=x+15,&am p; m∠5=4x+3. show all work for parts a, b, & c.

a. what is the value of xx?

b. what is the measure of \angle1∠1?

c. is \angle3∠3 complementary to \angle1? ∠1? explain.

a precentage of 6th graders. the population is all 6th graders. let me know if i'm wrong, i hope this ! : )

step-by-step explanation:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

493 would be the correct answer
