What are the missing angle measures in triangle ABC?

Finger [1]

we know that

In the right triangle ABC

∠ $A+$ ∠ $B=90$ ------> by complementary angles

Step $1$

Find the measure of angle B

we know that

$tan\ B=\frac{opposite\ side\ angle\ B}{adjacent\ side\ angle\ B}$

in this problem

$opposite\ side\ angle\ B=7in\\ adjacent\ side\ angle\ B=5in$

$tan\ B=\frac{7}{5} \\ \\ B=arc\ tan\frac{7}{5} \\ \\ B=54.5\ degrees$

Step $2$

Find the measure of angle A

$A+B=90\\ A=90-B\\ A=90-54.5\\ A=35.5\ degrees$

therefore

the answer is the option

35.5° and 54.5°

FlybynightSavings.com is offering a savings account that pays 33% compounded continuously. How much interest would a deposit of

pychu [463]

The exact calculations:
Principal, P=3000
interest rate = 33% per year
Period, t=10 years

Future value
$F=Pe^(it)$
$=3000e^(0.33*10)$
$=81337.92$

Interest
= future value - principal
= 81337.92-3000
= 78337.92 (to the nearest cent)
