HELP someone please!!!! i dont understand

Answer:

x = 65.03°

Step-by-step explanation:

To solve for x, we have to apply trigonometric ratio.

Recall: SOH CAH TOA

From the diagram, we know the following:

Reference angle = x

Hypotenuse = 45

Adjacent = 19

Since we know the Hyp and Adj, we would apply CAH, which is:

Cos x = Adj/Hyp

Plug in the values

cos(x) = \frac{19}{45}

x = cos^{-}(\frac{19}{45})

x = 65.0250346°

x = 65.03° (nearest hundredth)

Alana biked 12 miles in 48 minutes. What is Alana's speed in miles per minute?
marusya05 [52]
Question:- Alana biked 12 miles in 48 minutes. What is Alana's speed in miles per minute?

Answer:-

Set up a proportion.

12/48 = 1/x

Cross multiply.

12*x = 12x
48*1 = 48

12x = 48

12x/12 = 48/12 

x= 48/12
x= 4

Now, we have our final answer. x = 4

Final answer:- Alana bikes 4 miles per minute.

Anwser: <br> 36÷(1-9×1-4)+1+2
kkurt [141]
So this is a BIDMAS question so first you do what’s in the brackets so you have (1-9x1-4) and you have to do the multiplication first out of that to get (1-9-4) which is -12 so then you have overall 36 / -12 + 1 + 2 so you have to do the division first so do 36/-12 to get -3 and you have -3 + 1 + 2 which is 0 so your answer is 0.
