Explanation:


\underline{ \underline{ \large{ \tt{G \: I \: V \: E \: N}}}} :

  • ∠ AOE = a° , ∠EOD = 51° , ∠DOB = 90°


\underline{ \underline{ \large{ \tt{T \: O \: \: F \: I\: N\: D}}} }:

  • value of a


\underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I \: O\: N}}}} :

~Set up an equation and solve for a :


\large{ \bf{a \degree + 51 \degree + 90 \degree = 180 \degree}} [ Sum of angle in a straight line ]

~Add the numbers : 51° & 90°


\large{ \tt{a \degree + 141 \degree = 180 \degree}}

~Move 141° to right hand side and change it's sign


\large{ \tt{a \degree = 180 \degree - 141 \degree}}

~Subtract 141° from 180°


\large{ \tt{a = 39 \degree}}


\boxed{ \boxed{ \large{ \text{Our \:Final \: Answer} : \underline{ \tt{a = 39 \degree}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ
