<span>Which expression can be used to determine the side length of the rhombus?
The answer is the first option: 10/Cos(30°) Explanation:
1. As you can see in the figure attached, there is a right triangle and its hypotenuse (which is represented with the letter "x") is the side you want to calculate. So, you have:
Cos(</span>α)=Adjacent leg/Hypotenuse
<span>
</span>α=30°
<span> Adjacent leg=(20 in)/2=10 in
Hypotenuse=x
2. When you substitute these values into the formula, you obtain:
</span>
Cos(α)=Adjacent leg/Hypotenuse
<span> Cos(30°)=10/x
3. Therefore, you obtain the expression to determine the side length of the rhombus by clearing the hypotenuse "x", as below:
x=10/Cos(30°)

Answer:
c. 15cm^2
Step-by-step explanation:
1liter=1000milileter
times both sides by 2.07
2.07liter=2070 milileters
Answer:
25 is greater than -4(-4) because -4(-4) is 16, which is less than 25.
She needs a 56
87+92+76+89=344
400/5 = 80
400-344=56
