If you are given with all the tree sides of the triangle, you may solve for all the angles through the Law of Cosines,
                           c² = a² + b² - 2ab(cos C)
where angle C is the angle opposite the side c. You may use the same equation to get the values of the remaining angle. Additionally, if you already have one known angle, you can solve for the rest of the angles by Law of Sines,
                                   a / sin A = b / sin B = c / sin C

Can someone please help me on this problem
Dafna1 [17]

Answer:

Step-by-step explanation:

Perimeter is all sides added together.

l is length, w is width, and P is perimeter.

2l + 2w = P\\2(5x) + 2(x - 3) = 42\\10x + 2x - 6 = 42\\12x - 6 = 42\\12x = 48\\x = 4

Answer:

400 students

So 15 percent is 60 students

make an equation

0.15x=60

X stands for the total amount fo students and multiply that 0.15 becuase we know ti equals 60 and finding X will solve both problems

that’ll give you 400 students

if you check

400*0.15=60

So its correct

Question 9 of 25<br> 2 Points<br> What is g(x)?
patriot [66]
Composition means that you can plug g(x) into f (x). This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". And "( f o g)(x)" means " f (g(x))". That is, you plug something in for x, then you plug that value into g, simplify, and then plug the result into f. hope this helps.
