The triangles are similar. Find x.A. 3.5B. 2.24C. 1.6D. 3.6

Lerok [7]

When two triangles are similar, then the ratios of their corresponding sides will be equal:

so 2.4/3 = 2.8/x = y/4.5

Use the ratio that involves the x and the two values that are given:

2.4/3 = 2.8/x

Then, solve the equation for x to find the missing side:

2.4/3 = 2.8/x

(2.4 / 3 ) x = 2.8

x = 2.8 / (2.4/3)

x = 3.5

The correct option is A.

<h3>What is Interest ?</h3>

Interest is the amount of money received , when a certain lump sum amount is deposited.

It is given that the person is receiving ,

Interest = $5000 ,

after six months , every six month

Time Period = 10 years

Interest Rate = 4%

Compounded Semiannual

Let the principal amount be $x

Compound Interest is given by

Amount = P[ 1 + r/n]ⁿˣ

Here x is the time period

Therefore the Amount = x{ 1 +0.04/2}²⁰

x + 5000 *20 = x{ 1 +0.04/2}²⁰

x + 100000 = 1.486 x

x = $205783

Therefore he needs to have $205783 amount of money to receive $5000 every 6 months for 10 years.
