The value of cos 45 in a right angle triangle is 1/√2.

<h3 /><h3>What is the trigonometry ratio?</h3>

The trigonometry ratios are ratios that can be used to determine the side and angles of a triangle depending on the known parameter. The basic trigonometry ratios are denoted by the acronym: SOH CAH TOA

i.e.

Sin θ = opp/hyp
Cos θ = adj/hyp
Tan θ = opp/adj

From the given diagram, we are to find the Cos 45°

i.e.

θ = 45°

Let's recall the angle 45 45 90 theorem that states that right angles have the following values for the sides:

hypotenuse = √2
opposite = 1
adjacent = 1

Since

Cos θ = adj/hyp

Cos 45 = 1/√2

Pani-rosa [81]

Answer:

Option A- 294.85

Step-by-step explanation:

Given : Andrea is buying a car for $21,450 she will finance $16,450 of it with a 5 year loan at 2.9% APR.

To find : The monthly auto payment.

Solution : From the table we get that monthly car loan payment per $1000 borrowed when interest rate is 2.9% on a 60 month loan is

Monthly car loan payment per $1000 borrowed is $17.924

Per $1000 the finance is $A=\frac{16450}{1000}=\$16.45$

Monthly payment = Monthly car loan × Finance

$17.924\times 16.45=\$294.8498$

Therefore, Option A is correct.

The Monthly payment is $294.85.

2 less then 3 times a number is 9

Masteriza [31]

$\huge\boxed{\text{As an expression:}\ 3x-2=9}$

$\huge\boxed{\text{Solved for x:}\ x=\frac{11}{3}}$

Let's start with " $3$ times a number". We will use $x$ to represent the number. $3x$

" $2$ less than" is next. $-2$

Finally, "is $9$ ". $=9$

Put it all together to get an expression. $\boxed{3x-2=9}$

Now, let's solve for the unknown number.

Add $2$ on both sides of the equation. $3x=11$

Divide both sides of the equation by $3$ to isolate $x$ . $x=\boxed{\frac{11}{3}}$
