Answer:
87
55
Step-by-step explanation:
if you take 8+7 it equals 87 and i+f eqauls 55.
Answer:
Approximately 54°
Step-by-step explanation:
So we know Angle A, the side opposite to Angle A, and the side opposite to Angle B (the angle we want to find). Given these circumstances, we can use the Law of Sines.
The Law of Sines states that:

The variables do not really matter. Instead, it's more important that the angle corresponding to the side lines up with each other.
Anyways, since we know Side A, Angle A, and Side B, let's use the first and second ratios:

Plug in 80° for A, 11 for a, and 9 for b:

Cross multiply to solve for B:

Divide both sides by 11:

Use the inverse sine function. And finally, use a calculator to solve:

Answer:
x=15
Step-by-step explanation:
You need to do proportions.
Since 16/12 = 1.3333333333333333333,
than you need to divide 20 by 1.323333333, so 20/1.3333333333333= 15
Answer:
x ≥ 5
Step-by-step explanation:
Find the domain by finding where the equation is defined.
Interval Notation:
(5, ∞ )
Set-Builder Notation:
{x | x ≥ 5}
So, the answer is : x ≥ 5

Answer:
No
Step-by-step explanation:
The model shows two similar elements.
Although we do not know what the element is, we can conclude that the model is not a compound.
This is because the definition of a compound is when two different elements join.
However, the model has two similar elements, which forms a molecule, not a compound.
