Question

<ACD is an exterior angle of
∆ABC. <B =40°,<A =70°,then
<ACD = ​

Answer 1

Answer:

I don't know sorry actually I just need some point to ask questions

Answer 2

Step-by-step explanation:

In Δ ABC, ∠ACD = ∠A + ∠B (Exterior angle property) = 70∘ + 40∘ = 110∘ Hence, the measure of ∠ ACD is 110∘.
