Question

if the three angles of a triangle are absenti degree X + 20 degree and x minus 50 degree find the value of x also find the angles

Answer 1

To find the value of x and the angles of the triangle, set up an equation by using the fact that the sum of the angles in a triangle is always 180°. Solve the equation to find x, and then substitute x back into the angles to determine their values.

Step-by-step explanation:

To find the value of x and the angles of the triangle, we can use the fact that the sum of the angles in a triangle is always 180°. Let's set up an equation:

x + (x + 20) + (x - 50) = 180

Combining like terms:

3x - 30 = 180

Adding 30 to both sides:

3x = 210

Dividing by 3:

x = 70

Now we can substitute the value of x back into the angles:

Angle 1: x = 70°

Angle 2: x + 20 = 70 + 20 = 90°

Angle 3: x - 50 = 70 - 50 = 20°
