1. Write out the law of cosines and find the hypotenuse of triangle with 2 sides lengths equal to three and the included angle m
LUCKY_DIMON [66]

Answer:

1.) \sqrt{13.341}  ≈ 3.652

2.) I would say something about how the A in front of cos in the equation would change to 90, rather than stay 75 (in the equation for the step by step), but it would be easier to just use the Pythagorean theorem.

Step-by-step explanation:

I think we may have the same class so hopefully this helps:

1.) a^2 = b^2 + c^2 - 2bccosA --> law of cosines formula.

   a^2 = 3^2 + 3^2 - 2(3)(3)cos(75) --> plugged in numbers; when you draw the triangle, the included angle would be A, and the opposite side would be a. B and b, and C and c are opposite each other. In this case, a is the hypotenuse.

   a^2 = 18 - 18cos75 --> in between steps.

   a^2 = 13.341 --> more simplifying.

   a(hypotenuse) = \sqrt{13.341} or 3.652 --> answer

2.) This one is just an explanation: The 75 in the equation is the given angle, which is a. If this changes, it would just change in the equation too. And obviously, if it's 90 degrees, you can just use Pythagorean theorem a^2+b^2=c^2.

Good luck! :)

Find the measure of angle A
Neporo4naja [7]
Since 3x + 2 is on a. Straight line, is is equal to 180 degrees.
1) So, 52 + another number must equal 180 degrees.
2) You're answer would be 118 because 118 + 52 = 180
3) Angle A = 118

A film club initially had 300 members. However, its membership has since decreased by 6% each year. How many members did the clu
mezya [45]
F(x) = 300(1-.06)^5
f(x) = 300(.7339040224...)
f(x) = 220.17120672
After 5 years, the club should still have 220 members.
