Answer:
angle 1
Step-by-step explanation:
Using the trigonometric mnemonic SOH CAH TOA, we know that cos or cosine is the ratio between the adjacent side and hypotenuse side.
This means that if cos A = 0.48, A is the measure of the angle which it's relative adjacent side divided by the hypotenuse of the triangle will be around 0.48.
Let's try angle 2, cos (angle 2) = adjacent / hypotenuse = 7.8 / 8.9 = 0.876404494382 ≈ 0.87 ≠ 0.48. Since the proportions are not equal, this angle cannot be the one marked as A.
Since angle 3 is a right angle, the adjacent could be either side so it cannot be correct. Thus angle 1 is correct.
Answer: X = 12.1 units
Step-by-step explanation:
Solving the side x of the triangle just requires the Pythagorean theorem.
x^2 + 7^2 = 14^2
x^2 + 49 = 196
subtract 49 on both sides, to cancel the 49 on the left side.
x^2 = 147 units
extract the square root of each side.
X = 12.1 units

Answer:
Alright let's do this.
First Rewrite the question:
What operation do u use to find the cost of a drink and a popcorn for one person?
Ok when solving you need to take Maria's name and only use first letter.
I am just going to show the you how to do the question.
________________________________________________________
P= Popcorn (Cost: $8.00)
D= Drink (Cost: $5.00)
M (Maria) = $8 + $5 = (Answer)
F (Her Friend) = $8 + $5 = (Answer)
A quick way to solve to find the total cost for 2 people.
8 x 2 = 16
5 x 2 = 10
The total cost that Maria has to pay for her and her friend is $26.00.
The operation used is Addition or Multiplication.

Answer:
54 - 10y
Step-by-step explanation:
Distribute each of the 3 parenthesis
= 12y + 24 - 32y + 32 - 10y - 2 ← collect like terms
= 54 - 10y
