Answer: The answer is 24a + 6 because you add up the like-terms, so:

18a + 6a = 24a

8 - 2 = 6

I hope this helps!

Changle. Show all work. Round each length to the nearest tenth and each angle to the

Sedaia [141]

Answer:

Part 1) $BC=12.2\ units$

Part 2) $m\angle A=55^o$

Part 3) $m\angle C=35^o$

Step-by-step explanation:

Part 1) Find AC

we know that

In the right triangle ABC of the figure

Applying the Pythagorean Theorem

$AC^2=AB^2+BC^2$

substitute the given values

$AC^2=7^2+10^2$

$AC^2=149\\AC=12.2\ units$

Part 2) Find the measure of angle A

we know that

In the right triangle ABC

$tan(A)=\frac{BC}{AB}$ ----> by TOA (opposite side divided by the adjacent side)

substitute the values

$tan(A)=\frac{10}{7}$

using a calculator

$m\angle A=tan^{-1}(\frac{10}{7})=55^o$

Part 3) Find the measure of angle C

we know that

In the right triangle ABC

$m\angle A+m\angle C=90^o$ ----> by complementary angles

substitute the given value

$55^o+m\angle C=90^o$

$m\angle C=90^o-55^o=35^o$

Determine the actual cost, including interest, of a $3,450 used car with a down payment of $200 and 48 monthly payments of 75$ e

Fantom [35]

Answer:

$3,800

Step-by-step explanation:

$200 (down payment) + 48 x $75 (monthly payments)

$200 + $3600 = $3800

Since the original car was $3450, there was $350 in interest ($3800 - $3450 = $350)
