X = 78, because
1) The last angle (the one without the X, equals 24 degrees)
2) 180 - 24 = 156
3) 156/2 = x
x = 78

420-x=76 try that equation if not you might want a math tutor.
6. vertical
7. LSM and MSN are vertical angles

The woman is 61.5 inches tall.
This question is essentially asking for how many standard deviations the woman's height is away from the mean men's height.
Only 1 in 400 (or 0.25%) of men is shorter than our picky homegirl. If you think of a normal distribution of men's heights, this is the extreme left tail end. As a rule of thumb, +/- 3 standard deviations around the mean captures 99.5% of a population, leaving 0.5% outside of the interval (so, only 0.25% on each end). So we know that our girl refuses to marry anyone lower than -3 standard deviations from the mean.
All that's left is to plug in the given mean and SD:
69 -3(2.5) = 61.5 inches
Answer:
What is the magnitude and direction of the PQ−→− with tail and head points P(-6, 0) and Q(2, 4)? magnitude = √(64+16) = √80 = appr 8.9 , ruling out c.
