An Isoceles Triangle has base 6cm long and the opposite angle to the base is 50 degrees l. What is the size of the other angle?

65°

Step-by-step explanation:

From the question,

The base angle of an isoceles triangle are equal.

Let the value of the base angles = x°

Sum of angle in a triangle = 180°

⇒ x°+x°+50° = 180°

⇒ 2x°+50° = 180°

⇒ 2x° = 180°-50°

⇒ 2x° = 130°

⇒ 2x°/2 = 130/2

⇒ x° = 65°.

Hence, the size of the other angles is 65°
