Answer:

Step-by-step explanation:

every triangle, no matter what shape or size, will have all angles add up to 180 degrees so 180-40-60=80

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

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

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

Which statement best defines the two quantities that are measured to find the rate at which an airplane descends? A) The quantit

Schach [20]

The <em>correct answer</em> is:

C) The quantity of distance measured in feet depends on the quantity of time measured in minutes.

Explanation:

The rate of an airplane's descent would be found using the distance it descends and the amount of time that takes.

In this situation, the amount of time that passes causes the distance the plane descends to change; this means that the distance depends on the time.
