ahh ok yeah i remember doing that but idk what answer i got sorry. i think i just did sohcahtoa with the small triangle to get the other part of the angle and then added them together to get the whole angle and then just sohcahtoa again with the big triangle to get cd though if that helps

Did you get like 2.47? I feel like I did the same sort of thing…

What did you guys get for the 27km/h to m/s I got 7.5m/s or smth like that but not sure if it’s right

Yes I got that too

Im gonna try spill out as many answers as i can remember:
54 times for the pink counter
10 for coin question
12 for the score question
2+√5 for the cuboid
52.3 for angle of elevation
Coords of D was (4.6, 8)
Simultaneous eqs were (2, 1) and (-16/7, -3/7)
Upper bound for density was 9.56
Formula for Q was 3√t, % increase was 44%
Probability for two yellows was 5/9
Probability for at least one red was 219/220
Completing the square was 3(x-1)² + 2
Reflex angle was 288 degrees
The three graphs were C, F and A
Lmk if any are wrong and I should change them

I got all of those too. im pretty sure 4.6, 8 is the answer to the kite question i just checked it again

how did you do the density one? i got 3.04

Somewhere in the 70s? that's what it's usually like

For the y coordinate 8 and 4.25 or sommet fkr the x for the kite

yes the y value was 8 and the x value was something with a 4 but i cant remember it exactly

I think ur cuboid one is wrong. Think it is like 3 + root20

No you are wrong. It was definetly 2+√5

i thought angles in the same segment are equal so shouldnt it be 28 degrees for the circle theorem question

You needed to find the upper bound for the mass which was 265pi and the lower bound of the volume which i cant remember anymore and then get the density with that.

the volume was 4/3pi x 2.75to the power of 3
