please answer fastly

Answer 1

Answer:

We have the property of exterior and interior angles,

Exterior angle is equal to the sum of interior opposite angles.

From triangle ABC is figure above,

∠ACD=∠ABC+∠BAC

Let, ∠ABC=60∘

∠ACD=130∘

∴130∘=60∘+∠BAC

∠BAC=130∘−60∘=70∘ This is the value of the other opposite angle.
