Tasya [4]

Answer:

2·(a^2 + b^2) = (a + b)^2

2·a^2 + 2·b^2 = a^2 + 2·a·b + b^2

a^2 + b^2 = 2·a·b

a^2 - 2·a·b + b^2 = 0

(a - b)^2 = 0

a = b

Answer:

The angles are 45°, 60° , 75°

Step-by-step explanation:

<h3>Angle sum property:</h3>

Sum of all the angles of a triangle is 180°.

Equation:

3x + 5x + 4x = 180

Combine like terms,

12x = 180

x = 180/12

$\sf \boxed{x = 15}$

3x = 3 *15 = 45°

5x = 5* 15 = 75°

4x = 4 *15 = 60°
