Triangles LMN and NWR are right triangles. What is

Sever21 [200]

Answer:

NW = 15.6 cm

Step-by-step explanation:

If ΔLMN ~ ΔNWR then:

$\sf LN : LM = RN : RW$

$\implies \sf \dfrac{LN}{LM}=\dfrac{RN}{RW}$

$\implies \sf \dfrac{10}{24}=\dfrac{6}{RW}$

$\implies \sf 10RW=6 \cdot 24$

$\implies \sf RW = 14.4\:cm$

Find NW by using Pythagoras' Theorem:

$a^2+b^2=c^2$

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

a = RN = 6 cm
b = RW = 14.4 cm
c = NW

Substituting the given values into the formula and solving for NW:

$\implies \sf 6^2+14.4^2=NW^2$

$\implies \sf NW^2=243.36$

$\implies \sf NW=\sqrt{243.36}$

$\implies \sf NW=15.6\:cm$

Ravi deposits $600 into an account that pays simple interest at a rate of 4% per year. How much interest will he be paid in the

tamaranim1 [39]

Just find the interest paid after one year, and then multiply the result by 6 (years). This gives you the amount of simple interest.

The easiest approach would be to use the formula i = p r t. In this case p = $600, r = 0.04, and t = 6 years.

Does anyone know what this is ?

Natasha_Volkova [10]

Answer:

x = 2

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relations between trig functions and angle.

Tan = Opposite/Adjacent

tan(θ) = y/x

Sin = Opposite/Hypotenuse

sin(θ) = y/4

The given relation is ...

tan(θ) = 2·sin(θ)

y/x = 2(y/4)

2 = x . . . . . . . multiply by (2x/y)

_____

<em>Additional comment</em>

Then the angle can be found from the relation ...

Cos = Adjacent/Hypotenuse

cos(θ) = x/4 = 2/4 = 1/2

θ = arccos(1/2) = 60°

and the value of y is ...

y = 4·sin(60°) = 2√3
