Question

Find the value of x and tell which triangle it is.

Answer 1

x = 23

Obtuse scalane triangle

Explanation:

The sum of interior angles in a triangle is equal to 180

110+35+x+12 = 180

157 + x = 180 subtract x from both sides

x = 23

The given triangle is an obtuse scalane because it has no eqaual side lengths or angles measurment.
