We have to determine if triangle PQR is similar to triangle XYZ or not.

To determine if the two triangles are similar, we use three postulates

AA, SSS, SAS.

AA means two angles must be equal in both triangles.

From picture we can see that only one angle is given so we can't be sure about other angles.


SSS means all sides are in same ratio but we have been given value of only one side. So that is also not applicable.


SAS means ratio of two sides from both traingles is equal and both triangles share a common angle but that is also not the given case.


Hence final answer is D. "Cannot be determined".

Answer: Hello there!

this type of equations in one dimension (when all the factors are constants) are written as:

h =  initial position +  initial velocity*t + (acceleration/2)*t^2

First, let's describe the hunter's equation:

We know that Graham moves with a velocity of 1.5 ft/s, and when he is  18 ft above the ground, Hunter throws the ball, and because Graham is pulled with a cable, he is not affected by gravity.

If we define t= 0 when Graham is 18 ft above the ground, the equation for Graham height (in feet) is:

h = 18 + 1.5t

where t in seconds.

Now, the equation for the ball:

We know that at t= 0, the ball is thrown from an initial distance of 5ft, with an initial velocity of 24ft/s and is affected by gravity acceleration g, where g is equal to: 32.2 ft/s (notice that the gravity pulls the ball downwards, so it will have a negative sign)

the equation for the ball is:

h = 5 + 24t - (32.2/2)t^2 = 5 + 24t - 16.1t^2

So the system is:

h = 18 + 1.5t

h = 5 +24t - 16.1t^2

so the right answer is A
