Question

find the m angle ABD from adjoining figure?


​

Answer 1

Answer:

ABC is a triangle

angle BCA=50degree

angke BAC=70degree

angle ABD is an exterior angle

angle ABD=BCA+BAC

=70+50

120 degree

Answer 2

∠ABD = 120°

Given:

∠ACB = 50° and ∠BAC = 70°

To Find:

∠ ABD

Solution:

Exterior angle property: When a side of a triangle is extended, then the exterior angle formed by that side is equal to the sum of interior opposite angles.

From the Figure,

∠ABD = ∠BAC + ∠ACB     (By exterior angle property)

∠ABD = 70° + 50°

∠ABD = 120°

Therefore, the m angle ABD from the adjoining figure is 120°
