We have been given a diagram and we need to find the value of arc angle a.

According to one of the circle theorems the angle at the centre of a circle is twice the angle at  the circumference subtended by the same arc.

Therefore, arc angle a will be twice of the angle at circumference, that is, 34 degrees.

Therefore, value of angle a is:

a^{0}=2*34=68^{0}

1. What is the value of x? Show all of your work.
asambeis [7]
AB^2 + BC^2 = AC^2
AB^2 + 6^2 = square root 117^2
AB^2 + 36 = 117

Now subtract 117 from both sides
AB^2 = 81
AB = square root 81 = 9
\sqrt{81}  = 9
Therefore AB is 9 cms.
