Answer:
It is isosceles by the base angles theorem. It states that when the base angles are equal, the triangle is isosceles.
Step-by-step explanation:
unknown measure : 50°
Answer:
yes, ±2
Step-by-step explanation:
The x-intercepts are found by setting y=0 and solving for x:
x^2/4 = 1
x^2 = 4
x = ±√4
x = ±2
The x-values of interest are -2 and +2.
The discriminant of this equation is 49. The solutions for this equation are x=2 and x=-

I hope that helps.
Q equals cube root of 64, because if q to the power of 3 is 64, then you need to cube root 64 to just get q
