A scientist uses a submarine to study ocean life. • She begins 175 feet below sea level. • After descending for 6 seconds, she's 225 feet below sea level. Find the rate of change in the submarine's elevation in feet per second. Round your answer to the nearest tenth.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer
