The answer is ~0.556

Sin= opposite over hypotenuse.

To find the hyp., you use a squared plus b squared = c squared.

4+9=13

Square root of 13 is ~ 3.605

Now that you have your hyp, you can divide.

2 divided by 3.605 ~ 0.556 (rounded)

Hope this helps!!

The sine of the angle is the ratio of the opposite side to the hypotenuse. The hypotenuse of this triangle can be computed from the Pythagorean theorem:
.. AB = √(AC^2 +BC^2) = √(9 +4) = √13 . . . . cm
Then the ratio of opposite side BC to the hypotenuse AB is
.. sin(A) = BC/AB = 2/√13

Corresponds to the 3rd selection.

Answer:

Position of the submarine now relative to the water surface $=-47\ \frac{3}{4}$

Step-by-step explanation:

It says that the position of a submarine relative to the water surface was -32 1/4 feet . A downward navigational maneuver increased it's depth by 15 1/2 feet.

Now we need to find about what is the position of the submarine now relative to the water surface.

Downward navigation means we 15 1/2 is negative

so we will just add both values to get the final answer:

Position of the submarine now relative to the water surface = $-32\ \frac{1}{4}-15\ \frac{1}{2}$

$=-32\ \frac{1}{4}-15\ \frac{2}{4}$

$=-47\ \frac{3}{4}$

Answer:

<ABC = 15

< BAC = 150

Step-by-step explanation:

<C = <B since this is an isosceles triangle. We know this because AC = AB

<C = 15 so <ABC = 15

The sum of the angles of a triangle is 180

A + B+ C = 180

A + 15+15 = 180

A +30 =180

A = 180-30

A = 150

< BAC = 150
