Question

one angle of triangle ABC is 40 and the other two angle's are equal.Find the measure (value) of each equal angle.​

Answer 1

Answer:

first angle =40°

second and third=70°

Answer 2

Answer:

70°

Step-by-step explanation:

Sum of all angles of triangle : 180°

One of the angles of the triangles are : 40°

The sum of the other two angles : 2x (As the other 2 angles are same.)

⇒ 2x + 40 = 180

⇒ 2x = 140

⇒ x = 70°

⇒ ∴ The measures of the other two angles = 70°
