The three angles of a triangle create the extended ratio 2:2:5. What is the measure of the largest angle?
Dima020 [189]

Answer:

100°

Step-by-step explanation:

The ratio of angles of the triangle is 2:2:5. We know that the angle sum property of the triangle is 180°. So that , let the ratio be 2x : 2x : 5x .

=> 2x + 2x + 5x = 180°

=> 9x = 180°

=> x = 180°/9

=> x = 20°

Here the largest ratio is 5x . Therefore the largest Angle is ,

=> Largest Angle = 5x

=> Largest Angle = 5 × 20°

=> Largest Angle = 100°

<h3>• Hence the largest Angle is 100° </h3>

You put $600 in an account with a simple interest rate of 2.5%. How long does it take for the account to earn $45?
MA_775_DIABLO [31]

Answer:

3\ years

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=?\ years\\ P=\$600\\ A=\$600+\$45=\$645\\r=0.025

substitute in the formula above  and solve for t

645=600(1+0.025t)

t=[(645/600)-1]/0.025=3\ years
