Answer 1

Let B and C be the vertex having exterior angles 104 and 136

respectively.

Ext∠B=104 °

and Ext∠C=136 °

Using theorem "Exterior angle is the sum of interior opposite angles", we get

∠A+∠B=104°.......... (1)

∠A+∠C=136° .......... (2)

Adding equation (1) and (2)

∠A+∠B+∠C=240°

As we know, ∠A+∠B+∠C=180°

Hence,

∠A=240 °−180° =60 °

From equation (1),

∠B=104° −60° =44°

From equation (2),

∠C=136° −60° =76°

Hence, angles of the triangle are ∠A=60° ∠B=44° and ∠C=76°
