Question

find the angles of triangles if sum of
two angles of a triangles is 80° and the
difference is 20​

Answer 1

Answer:

I hope it is helpful for you

Step-by-step explanation:

Consider a △ABC,

then according to the given condition we have:

∠A−∠B=20

∠A+ ∠B= 80

⇒ 2∠A= 100

⇒ ∠A= 50

⇒ ∠B= 30

Using the sum of all the angles of the triangle is

180

We have:

∠A+∠B+∠C=180

⇒ 50+ 30+ ∠C= 180

⇒ ∠C= 100

Hence

∠A=50

∠B=30

and

∠C=100
