Question

the vertical angle of an isosceles triangle is 70 degree find the other angle​

Answer 1

Answer:

other two angles are of measure 55°

Step-by-step explanation:

in an isosceles there are two equal angles and a vertical angle

so let the other angle be x and x ( as both angles are equal)

sum of all angles=180°

⇒x+x+70°=180°

⇒2x+70=180

⇒2x=180-70=110

⇒x=110/2

⇒x=55°

Answer 2

Answer:

55

Step-by-step explanation:

Hence, the vertical angle of the isosceles triangle is 70 degrees. So, the correct answer is “Option C”. Note: In an isosceles triangle, the vertical angle is the angle other than the two equal angles (also known as the base angles). Two of the angles of the isosceles triangles are always equal.
