@anlikadraj The correct answer is 55
2 + (2×4) = 10
3 + (3×6) = 21
4 + (4×8) = 36
5 + (5×10) = 55

@PBalian11 @Quizmania0 Thank you! I watched the video , and saved it so I can watch it again "as needed ".

@ursharper Could you repeat the question?

@PBalian11 @Quizmania0 Wow, great explanation!
After reading it 4 times, Google, Grok, and awakening long-dormant brain cells, I think I understand.
As long as C is on the circle (length of BC does not change) then ACD will always be 33 (for this example)?

@farman4x The answer is 16

@Infinite_Logiz Not enough information is given.
Are we assuming that the bottom angles are right angles?
Because any good mathematician knows you cannot assume.
This diagram needs more info.

[Eric @5900Eric]

@SalishAlbert The correct answer is X = 10
The angles of the large triangle are 100-70-10.

[Eric @5900Eric]

@soran0312_ The answer is 40
Add up 22 + 25 + 33 = 80
There's two of each shape in those.
But one of each shape in the final.
So 80 divided by 2 is 40.

[Eric @5900Eric]

@soran0312_ The answer is 120

@TheMathzonee Diagram is not to scale. Use the numbers, not how it looks.
The answer is 55.

[Eric @5900Eric]

@SolvingForZ M = 60
Diagram is not to scale.

[Eric @5900Eric]

@Quizmania0 The diagram is wrong.
It is an impossible triangle.
The large triangle has angles of 80 - 80 - 60, which add to 220.
This question is a FAIL.

[Eric @5900Eric]

@josephmpotter @IQTestBrain If a = +2, b cannot be 10. It must be 6.
If a = -2 , b cannot be 6. It must be 10.
So 8 is not a possible answer.
Also, your signs are wrong. A is either (-4) or (-12).

[Eric @5900Eric]

@IQTestBrain Two possible answers
a = 2, b = 6, a - b = (-4)
or
a = (-2), b = 10, a - b = (-12)

@AiWithliza Two possible answers
121
or
sqrt(11)
