1) Work out the value of x.
2) Give reasons for your answer.

Please!

x = 60

Step-by-step explanation:

Since the 3 sides of the triangle are congruent, then the triangle is equilateral with interior angles congruent and equal to 60°

x and the angle on the right of the triangle are alternate and congruent, so

x = 60

  center: (1/2, 6)

  radius: √5

Step-by-step explanation:

The standard form equation for a circle of radius r and center (h, k) is ...

  (x -h)^2 +(y -k)^2 = r^2

When we compare this to the given equation:

  (x -1/2)^2 +(y -6)^2 = 5

we see that h=1/2, k=6, and r^2=5.

The center is (h, k) = (1/2, 6); the radius is √5.
