Answer:
x = ±20
Step-by-step explanation:
x^2 -1=399
Add 1 to each side
x^2 = 399+1
x^2 = 400
Take the square root of each side
sqrt(x^2) = ±sqrt(400)
x = ±20
A right triangle has one 90°angle, and the sum of the 2 other angles equals 90.
an equilateral triangle has all sides and angles of the triangle congruent. each angle will equal 60°
an isosceles triangle has 2 congruent sides and 2 congruent angles.
a scalene triangle has no equal sides or equal angles.
an obtuse triangle has one angle that is greater than 90°
an acute triangle has all angles that are less than 90°
Hope this helps you classify your triangles!
