Question

Q4 Find c, given that a = b = c.

​

Answer 1

Answer:

60°

Step-by-step explanation:

Since, XOY is a straight line,

Angle XOY = 180° -----1)

Also given that, a = b = c ----2)

Now, a+b+c=180° (As XOY is a staight line) ----3)

From 2) and 3),

3c=180 (Taking a and b as c, as all are equal)

Therefore, c = 60°
