Answer:
l = gt²/(2π)²
Step-by-step explanation:
if T = 2π√l/g
squaring both sides
(T)² = (2π)² × (√l/g)²
T² =4π² × l/g
T² = 4π²l/g
using cross multiplication techniqes
gT² = 4π²l
divede both sides by " 4π²"
gT²/4π² =4π²l/4π²
gT²/4π² =l
l = gT²/(2π)²
that is the final answer.
now, let's notice the minor arc of 26x°, let's recall that a circle has a total of 360°, thus if the minor arc is 26x°, then the major arc has to be the difference of 360 and that much, namely 360 - 26x.
Check the picture below.
It’d be 90 degrees I think
