Answer:
8.090169944 or rounded 8.1
Step-by-step explanation:
Use SOH CAH TOA
Look at x and where it is and what you have.
First thing is to get an angle to use, 36, then to set up your equation.
___(36)=___
Figure out what you have.
You have the hypotonouse, 10, and need the adjacent,x, so you use the equation that involves H for hypotonouse and A for adjacent.
You set up your equation using COS, as you are using CAH.
Cos(36)=x/10
X is over ten sure to CAH C-cos A-adjacent and H-hypotonouse
Switch it around to make it equal to x
10*Cos(36)=x
You input it into your calculator. [10] [COS] [36] [ENTER] and you get the answer.
Round however is needed.
Answer:
Expression:

Value where y = 20
2
Step-by-step explanation:
Let's take a look at the sentence:
3 less than the quotient of y and 4
3 less indicates that you will subtract
- 3
Quotient means the result of division.

So if we combine the two, it says 3 less than the quotient so we subtract 3 from the quotient:

So if y = 20, we just substitute the y with 20
