x = 180 - 64 - 58 = 58°
Acute ..Isosceles
Second one :
We have an equilateral triangle ...each interior angle = 60° = x
Acute...Equiangular....Equilateral....Isosceles [ some people will debate the "Isosceles" classification...."Isosceles" is often defined as a triangle having EXACTLY two sides of equal length ]
Last one
x = [180 - 48 ] / 2 = 132 / 2 = 66°
Acute...Isosceles
