Question

(3) In the given figure, Find x, С (2x + 15)° |(x + 10)• (3x + 5)2 B A​

Answer 1

We know that angle sum property of a triangle equals 180⁰.

$∴∠A + ∠B + ∠C = 180\degree$

$(x + 10) + (3x + 5) + (2x + 15) = 180\degree$

$6x + 30 = 180\degree$

Dividing both sides by 6,

$x + 5 = 30$

$x = 25$

$∠A = x + 10 = 35\degree$

$∠B = 3x + 5 = 80\degree$

$∠C = 2x + 15 = 65\degree$
