Question

find x in a triangle ABC if angle A is equal 53 and external angle acd is equal 106​

Answer 1

Step-by-step explanation:

Two objects of same masses, one moving in straight path and other in circular path with same velocity. Is kinetic energy of both the objects same?

Answer 2

Step-by-step explanation:

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

Hence, In this case ∠A and ∠B

So,

∠A+∠B=140

∘

as ∠A=∠B

or,2∠A=140

∘

∠A=∠B=70

∘
