That big triangle is made up of 2 congruent 30-60-90 triangles with each base measuring 4.5. You could use the tangent ratio to get tan60 = x / 4.5. Multiply both sides by 4.5 to get 4.5 tan60 = x. Do that on your calculator in degree mode to get that x = 7.79 or 7.8
The answer is square root 6/2
Step-by-step explanation:
= 2*5^4 + 4*5^3 + 4*5^2 + 0*5^1 + 3*5^0
= 2*625 + 4*125 + 4*25 + 0*5 + 3*1
=1250 + 500 + 100 + 0 + 3
= 1853 base 10
1853 divided by 8 = 231 r 5
231 divided by 8 = 28 r 7
28 divided by 8 = 3 r 4
3 divided by 8 = 0 r 3
Therefore the answer is 3475 base 8
300*.08= 24
300+24= 324
24*4= 96
324+96= 420
420 athletes are expected
