Hi! If the submarine is descending at a rate of 15 meters per minute, then it has descended 900 meters in one hour (15*60=900). This would mean that option A is FALSE and option B is TRUE since halfway to the submarine's descent is 1 hour.

In half an hour, the submarine has descended 450 meters therefore option C is also TRUE. After 2 hours, the submarine has descended 1800 meters. Therefore, options D and E are also TRUE. Option F is FALSE since 450*3 is not equal to 1800.

ANSWER: B, C, D, E

Which theorem would you use to prove ABE ~ DCE?
Pachacha [2.7K]
Answer: Choice C) AA similarity

------------------------------------------------------------------------------
------------------------------------------------------------------------------

We are given that angle ABE = angle ECD since they are both right angles (square marker)

Angle AEB = angle CED as they are vertical angles

we have two pairs of congruent angles, leading us to be able to use the AA (angle angle) similarity theorem

4. The figure represents a ramp. Find the height of the ramp.
IgorLugansk [536]
Notice that the triangle is a right triangle, because of the right angle. By the Pythagorean Theorem, a^2+b^2=c^2. Then 15^2+b^2=17^2\implies 225+b^2=289\implies b^2=64\implies b=8, d. 8 m
