The actual resolution required is about 25 micro-arcseconds (this should NOT be the answer you got above). Based on this, how big of a telescope (i. e., telescope diameter) do you need to observe the event horizon of M87*? Give your answer in meters. Use the following formula: LaTeX: \theta=\:1.22\:\frac{\lambda}{D}θ = 1.22 λ D, where LaTeX: \thetaθ is the resolution stated above but you must convert it to radians first, LaTeX: \lambdaλ is the wavelength at which we are observing, and D is the diameter of the telescope. D and LaTeX: \lambdaλ will have the same units. Assume that we are observing at a wavelength of 1 mm. (HINT: D will be in mm too so convert your answer to meters!) Be careful with the units in this question!
