Answer:
a.11.8
Step-by-step explanation:
You can plug in any of the numbers with second cos to figure this out. cos^-1 (10/11.8) is equal to 32. Which is the angle. So A has to be the answer.
Also cant be c or d because the hypotenuse is larger then any of the other sides.
With B it is about 35

Number of girls in the school = 675 * 0.56 = 378
2/9 of these are over 16 , so this is:-
378 * 2/9 = 84 Answer
Well, to find the slope, you'd have to rearrange the equation so that it is in slope-intercept form, y=mx+b.
3x-y=0
-y=-3x+0
y=3x+0
The slope would be 3/1, and the line intersects y at point (0,0).
Hope this helps :-)
