Question

Find the sum of angle 1, angle2, angle3, angle 4, angle 5 and angle6.​

Answer 1

Step-by-step explanation:

They both are triangles

so by angle sum property

sum of angle 1, angle2, angle3, angle 4, angle 5 and angle6. = 180° + 180° = 360°

Pls mark me BRAINLIEST

Answer 2

Step-by-step explanation:

If u will say deeply, then it has two triangles.

First triangle consist of angle 1, 5 and 3

Another triangle consist of angle 2, 6, 4

Now in first triangle,

angle 1 + angle 5 + angle 3 = 180°

(angle sum property of∆). —(Eqn - 1)

Now in another ∆,

angle 2 + angle 6 + angle 4 = 180°(angle sum property of∆). —(Eqn - 2)

On adding Eqn 1 and 2, we get

=>angle 1 + angle 5 + angle 3 + angle 2 + angle 6 + angle 4 = 180° + 180°

=>angle 1 + angle 2 + angle 3 + angle 4 + angle 5 + angle 6 = 360°

That's the method of solution!
