Option A and B
Step-by-step explanation:
sides of the triangle have been given as 15, 15.8, 30 units.
angles of the same triangle has been given as 70°, 80°, [180-(70+80)] or 30°.
Here we see all sides and all the angles of the given triangle have different measures ( all the three sides and angles are different )
By the definition of scalene triangle the given triangle will be scalene.
Since all three angles of the triangle are acute angles (less than 90°).

Answer:
±2 sqrt(3) =x
Step-by-step explanation:
12 - x^2 = 0
Add x^2 to each side
12 - x^2 + x^2 = x^2
12 = x^2
Take the square root of each side
±sqrt(12) = sqrt(x^2)
±sqrt(4*3) = sqrt(x^2)
±sqrt(4) sqrt(3) = x
±2 sqrt(3) =x
