Question

in a triangle an exterior angle at a vertex is 85⁰and its one of the interior opposite angles is 45⁰.find the angle of the triangle ​

Answer 1

Step-by-step explanation:

hope it helps u.

look carefully

Answer 2

Answer:

In ∆ ABC

Angle ACD=85°

Let's Suppose Angle BAC=45°

So, Angle CBA= measure of Angle ACD - measure of Angle BAC

Angle CBA=85°-45°=40°

Sum Of All Angles Of Triangle=180°

Angle BAC+Angle CBA+Angle BCA=180°

45°+40°+x =180°

85°+x=180°

x=180°-85°=95°
