Answer:

The adjacent angles are: 72 and 108

Step-by-step explanation:

Given

Angle Ratio = 3 : 2

Required

Find the measure of each angle

Let the angles be x\ and\ y.

Such that:

x + y = 180 --- adjacent angles of a parallelogram

and

x : y = 3 : 2 --- given

Convert to fraction

\frac{x}{y} = \frac{3}{2}

Cross Multiply:

2x = 3y

Make x the subject:

x = \frac{3}{2}y

x + y = 180 becomes

\frac{3}{2}y + y = 180

Take LCM

\frac{3y + 2y}{2}= 180

\frac{5y}{2}= 180

y = \frac{2}{5} * 180

y = 0.4 * 180

y = 72

Recall that:

x = \frac{3}{2}y

x = \frac{3}{2} * 72

x = 1.5 * 72

x = 108

<em>Hence, the adjacent angles are: 72 and 108</em>

You are given a choice of taking the simple interest on $100,000 invested for 2 years at a rate of 3% or the interest on $100,00
valentinak56 [21]

Answer:

Step-by-step explanation:

the simple interest formula= principal* interest rate*time

simple interest : 100000*%2*2 years

simple interest= 4000 dollars

compound quarterly : A=principal(1+r/4)^t

since it is quarterly and have 4 quarters in a year, and 8 in two years.

compound quarterly: 100000(1+0.03/4)^8=106159.88

it is better to invest with compound interest because it add 6159 dollars in two years to the investment of 100000 dollars.

the difference between the interest: 6159.88-4000=2159.88
