m<PJK = m<DJB bec of vertical angles. Substitute the expressions with x and solve for x. Then use x to get the measure of angle PJK Then m<PJK + m<KJD = 180

The two angles I marked are called vertical angles. Vertical angles are congruent. That means they have the same measure. dw:1359930401555:dw

Since the measure of one angle is 3x  40 and the other one is 2x  10, and the measures are equal, that means 3x  40 = 2x  10 If you solve this equation, you get the value of x.

Do you follow so far?

Yes, so it's 3x  40 = 2x  10 +40 +40 3x = 2x + 30 2x 2x x = 30 Is that right?

Good. Now since the measures of one angle is 3x  40, and x = 30, what is the measure of the angle?

No wait, sorry it's 3(30)  40

If you break down the problem into simple steps, it's not that complicated. You're welcome.
