TryingForMHS also dont you have to do 11 + 4 then add a 1 as the x axis
yes, I have a couple more:
Question 14
Consider a right angled triangle where one of the non right angles is α and
tan α= 4 If the length of the adjacent sides is 7 what is the length of the hypotenuse?
A: √65
B: 4/7
C: √800
D: √833
E: 28
Question 31
y = 6x + 12
then, x − 12/x − 3 =
A: y/y+9
B: y−24/y−15
C: y−60/y−6
D: y−84/y−30
E: y−12/y−3
I guess its a, thanks!
Skyward1264 i think its either c or d

for 14, its easier than you think, so according to the trig function Tan, Tan of theta = opp/adj. So, we already know the adjacent is 7. So we can plug that in denominator, now, what number divdes by 7 to get 4. This is of course, 28. Now we know two sides, so now we can use pythag theorem where a2+b2=c2. So, 282+72 = sqrt833
oh and for 31, the answer is d because just have to make x the subject of the first equation so it would be 6x=12-y. And to make the next equation able to be substituted with x you must times the top and bottom by 6 so you can substitute 12-y or y-12 in it.
ok thank you soo much.Thats good news haha
so methodical
haha
MMHS What im dumb explain it please
How many do u guys get approximately out of 60 for verbal? And for numerical out of 50?
