Question

One angle of the triangle is 130 degree .if we draw a circle with diameter as the opposite side of this angle examin wheather the vertex in the circle ,out side the circleor on the circle

Answer 1

Answer:

It's your answer.....!!!!!

Step-by-step explanation:

Given: In ΔABC, ∠A = 60° and ∠B = 70°

Using angle sum property:

∠A + ∠B + ∠C = 180°

⇒ 60° + 70° + ∠C = 180°

⇒ 130° + ∠C = 180°

⇒ ∠C = 180° − 130°

= 50°

We know that angle in a semi circle is a right angle.

If AB is the diametre of the circle then ∠C should be equal to 90°.

However, here ∠C is less than 90°. Therefore, vertex C will lie outside the circle.
