Westkost [7]3 years ago

Answer:

(3x+14)+(8x-21)=180°

Step-by-step explanation:

Angles with measures 3x+14 and 8x-21 (or pmore precisely, vertical angle to angle 8x-21) are supplementary (add up to 180°).

Converse to same-side interior angles theorem states that If two same-side interior angles are supplementary, then l║p.

So, to prove that lines l and p are parallel, you have to show that angles 3x+14 and 8x-21 are supplementary.

Thus,

(3x+14)+(8x-21)=180°

Catherine invested a principal of $1,650 in her bank account with interest rate 3.1 % How much interest did she earn in 14 years
never [62]

Answer:

$693

Step-by-step explanation:

Catherine invested a principal of $1,650 in her bank account with;

interest rate of 3.1%

How much interest did she earn in 14 years?

To find the amount accumulated in the 14 years, we use the formula:

A = P(1 + rt)

Where A is the amount accumulated, P is the principal, r is the interest rate and t is the time.

A = $1650(1 + \frac{3}{100}(14))

A = $1650 + $693 = $2343

Interest = Amount (A) - Principal (P) = $2343 - $1650 = $693
