AO = OB = AB =>  a

Area = 1/6 [ a² pi - a² (3√3) / 2] 

Arc GHF = 360º - ( 180º - 56º ) 

How do you know what's behind that blurriness?

I don't see a word integer 

If a side TO is the base, the possibilities are limited   1,2,3.......21

But, if a side TO  is one of 2 legs, the possibilities are practically endless    6,7,8.................∞

( I hope that I understood the question correctly. This time I have more questions than answers...)

∠DAH = ∠BAC

x = (144 + 124) / 2

@P = $3/4($ 2rpi ) +& 2r 

If the questions can be "camouflaged", so can the answers.

Perimeter  P = 2*10pi

In triangle ABC, AB = BC = 25 and AC = 40. What is sin∠ACB?

Let M be a midpoint of AC

BM = sqrt( BC² - MC² )

sin∠ACB = BM / BC

x² + 3x + 20 = 360

If x = 17 then    m / n = 11 / 79  

SP + PQ = 114/2      solve for x
