U must’ve rounded ur values too early
That multiple choice said 4 right congruent isosceles triangles. A rhombus doesn’t have that
I thought the multiple choice was ok but the short answers…forget about it haha
There’s another discussion posted about this. It has some information on it @marina181
How did you do the last one?
How did you do it
For the last question it said the altitude is constant which means it be altitude doesn’t change and it also said it has to fly over her head which means she is in between the two points (the initial point when the angle of elevation is 15 degrees and the last point was when the angle of elevation was 52 degrees) so you can just make two triangle that has the same height which was the altitude and use the tangent one has 15 degrees opp the height and the other one has 52 degrees opp the height then you solve for the individual distance and add them
Did it say 4 right congruent isosceles triangles? Or did it just say isosceles?
Can somone write all the answers they remember, that are right for sure
I remember it saying 4 right isosceles congruent. I ended up picking that at the answer, but I’m pretty sure that’s wrong
For the mc was it 32pi or 48pi???
Rethinking that Frieda question… Did it say that the plane flew over head? If it did then 18443 isn’t right and 210 isn’t right either
Yeah, it did fly over her head which is why i assumed it was sin instead of tan(to find the hypotenuse instead of a leg like you would with tan). It makes more sense that you would find the distance to the plane(hypotenuse) and then subtract the two distances to see how far it traveled. Using tan doesn’t get the distance to the plane though. My answer was 184 mph but everyone is saying 210 mph so i just assumed i was wrong. But it still doesn’t make sense to me why you would use tan instead of sin…
Yeah I remember it said something like it flew directly over the head
I got 321 because I made two separate triangle with 15 and 52 degrees opposite the altitude and added the answers
Now that I think about it, that seems right…wow, just when I thought I got it right with the 210 mph. I think they should have given us a diagram. Who was reading that closely by the end of that brutal test??
How many points do you think they’ll take off if we said 18442 and 210 mph? I’m hoping only 1-2 bc the trig was right and the speed is correct on error.
And to clarify about the isosceles question, the question did say right isosceles triangles? So that choice wasn’t an answer? I could use those points, hoping I didn’t get that one wrong too…
I think if you have the correct work they will give you like 2-3 points
For the rhombus I thought rhombus doesn’t have 4 Isosceles triangle but now when I think about it isn’t isosceles right triangle technically correct because square is a rhombus and it has 4 isosceles right triangles
Not all rhombuses are squares though…And I believe the question was asking what could be used to show a parallelogram is a rhombus.
I’m so annoyed about that airplane question. I feel like almost everyone made the same mistake as me so I thought I was right for a while.
Also, can anyone retake it in august just to see if you can get a better score? Or do you have to fail?
I think you have to fail and the August one is much harder than this one
Do you think if 321 is the answer?
