Question

if one angle of a triangle is twice the another angle and 3rd angle is 45⁰. Then the angles are ​

Answer 1

Step-by-step explanation:

let,

one of the angle of a traiangle be x

and another angle be 2x

measure of the 3rd angle is 45°

We know that,

Sum of all the angles in a triangle = 180°

therefore,

x + 2x + 45° = 180°

3x = 180° - 45°

x = 135 ÷ 3

x = 45

so, the measurement of three angles in the triangle are 45° , 45×2 = 90° , 45°

Hope it helps you!!

Answer 2

Answer:

let one angle of a triangle be x

therefore another angle is 2x

and third angle is 45°

therefore

x+2x+45°=180°............sum of angle of triangle is 180°

therefore 3x+45°=180°

3x=180°-45°

x=135°/3
