Question

One of the angles of a triangle is 60 degrees and the angle opposite to them is equal, then find the value of each angle of the triangle.

Answer 1

Answer:

60°

Step-by-step explanation:

• let the equal angle be x
• one angle = 60°

sum of interior angles of a triangle = 180°

$x + x + 60 = 180 \\ 2x + 60 = 180 \\ 2x = 180 - 60 \\ 2x = 120 \\ x = \frac{120}{2} \\ x = 60$

• the other two equal angle = 60°
