Answer:
3/2
Step-by-step explanation:
Set this up as follows...
12x - 10 = 7x + 20
solve for x
X is 6
sub VW=7X with 7•6
VW=42
check by subbing also for UW
72 - 10 is 62
uV plus VW equals 62. it checks out.
Hmmm recall, p=3, and "p" is the distance from the vertex to either, the focus or directrix, so if the focus is 3 units to one-side of the vertex, the directrix is 3 units to the other side
check the picture below
X + x + 165 = 1315
2x + 165 = 1315
subtract 165 from both sides
2x = 1150
divide both sides by 2
x = 575
January 575
February 575 + 165 = 740
Answer:
57.6°
Step-by-step explanation:
It is always helpful to draw a picture. Also, you need to memorize all the definitions of the trig functions. For example,
sine of an angle = opposite side/hypotenuse
In your case, SQ is opposite side to angle R and QR is the hypotenuse
Therefore, sin R = 6.5/7.7
m∠R = arcsin (6.5/7.7) = 57.6°
