Answer:
C) 120 degrees
Step-by-step explanation:
m<A + m<B + m<C = 180
45 + m<B + 15 = 180
m<B + 60 = 180
m<B = 120
120, 90, 30 if you're going from the depths of the water to water level
The number could have been 8.699999999 so yeah there
Answer:

Step-by-step explanation:
Before we find x, we need to set up this triangle a little more. We need to find the triangle's altitude before we can solve for x. We will use the heartbeat method to find the altitude.
Let altitude = y; solve for y:




Now that we know the altitude, we can use the Pythagorean Theorem to find the hypotenuse (x).





Since c and x are the same; c is just the hypotenuse in the Pythagorean Theorem.

Answer:
use quarts. it is more precise because it is an smaller measurement
