Yakvenalex [24]

Answer:

Each of them spent $9.35 on meal.

Step-by-step explanation:

Jacob and his three friends ordered an individual pizza and a drink for $6.19.

Total cost of pizza and drink = 6.19 × 4

= $24.76

They also ordered bread sticks for $4.25

Tax on the bill was = $2.39

Tip amount was = $1.50×4 = $6.0

So the total billed amount will be = 24.76 + 4.25 + 2.39 + 6

= $37.4

Since there were four persons including Jacob.

Therefore, each person spend on meal = $\frac{37.40}{4}$

= $9.35

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

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

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