Answer:
a = 22
Step-by-step explanation:
![cot \: 4a = tan \: (a - 20)....(given) \\ \\ \implies \: tan(90 - 4a) = tan \: (a - 20) \\ [\because \: cot \theta = tan(90 \degree - \theta) ]\\ \\ \implies (90 - 4a) = tan(a - 20) \\ \\ \implies \: 90 + 20 = 4a + a \\ \\\implies \: 110 = 5a \\ \\ \implies \: a = \frac{110}{5} \\ \\ \huge \red{ \boxed{\implies \: a = 22}}](https://tex.z-dn.net/?f=cot%20%5C%3A%204a%20%3D%20tan%20%5C%3A%20%28a%20-%2020%29....%28given%29%20%5C%5C%20%20%5C%5C%20%20%5Cimplies%20%5C%3A%20tan%2890%20-%204a%29%20%3D%20tan%20%5C%3A%20%28a%20-%2020%29%20%5C%5C%20%20%5B%5Cbecause%20%5C%3A%20cot%20%5Ctheta%20%3D%20tan%2890%20%5Cdegree%20-%20%20%5Ctheta%29%20%5D%5C%5C%20%20%5C%5C%20%5Cimplies%20%2890%20-%204a%29%20%3D%20tan%28a%20-%2020%29%20%5C%5C%20%5C%5C%20%20%5Cimplies%20%5C%3A%2090%20%20%2B%2020%20%3D%204a%20%2B%20a%20%5C%5C%20%20%5C%5C%5Cimplies%20%5C%3A%20%20110%20%3D%205a%20%5C%5C%20%20%5C%5C%20%5Cimplies%20%5C%3A%20a%20%3D%20%20%5Cfrac%7B110%7D%7B5%7D%20%20%5C%5C%20%20%5C%5C%20%5Chuge%20%5Cred%7B%20%5Cboxed%7B%5Cimplies%20%5C%3A%20%20a%20%3D%2022%7D%7D)
