The side opposite the 30o angle is 1/2 W. That is just a property of a 30 - 60 - 90 triangle. Use that fact to set up the pythagorean relationship.
w^2 = (1/2 w)^2 + (7 * sqrt(3)) ^2
w^2 = 1/4 w^2 + 49*3
w^2 = 1/4 w^2 + 147
3/4 w^2 = 147
w^2 = 147 * 4/3
w^2 = 49 * 4 = 196
w = sqrt (196)
w = 14

Answer:
y=9
x=26
Step-by-step explanation:
5x-17+3x-11=180
8x-28=180
8x=208
x=26
5(26)-17
130-17
113
2y+5+90=113
2y+95=113
2y=18
y=9
Answer:
Any line with a slope (m) of 2/5
Step-by-step explanation:
It is easy to find the slope of a perpendicular line when one of the lines is given. All you have to do is flip the fraction (If it is a whole number, set under 1.), and change the sign (negative to positive, and vice versa).
In this case the perpendicular slope of (-5/2) is 2/5.

Answer:
Option B
Step-by-step explanation:
Only lines which are parallel to the line which connects the given two points will neve r intersect,
parallel line has same slope
the slope of the line which connects the given two points is, 5/2
and the line is option B also has the same slope, so those two lines will never intersect each other.
