Question

the angles of a triangle are 2x, 3x, and 4 degrees find the value of x

Answer 1

Sum of angles in triangle will always be 180°.

2x° + 3x° + 4° = 180°

Subtract 4° from both sides of the equation,
2x° + 3x° = 176°
5×° = 176°
x° = 176°/5
= 35.2°

Value of x is 35.2 (without the degrees sign).

Hope this helps! :)
