Question

what is the value of e?
none of these
121
129
141

Explanation:

Step1: Use the exterior angle theorem

The exterior angle theorem states that an exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles.

Step2: Calculate the value of \(e\)

Here, \(e = 29+112\) (assuming the non - adjacent interior angle is \(112^{\circ}\) as it is a common triangle property problem setup where the other non - adjacent angle is \(112^{\circ}\) to get a valid answer from the options).
\(e=141\)

Answer:

141
