Step-by-step explanation:

60 \degree + x = 180 \degree \\ ..(straight \: line \:  \angle s) \\ x = 180 \degree - 60 \degree  \\ x = 120 \degree  \\  \\ x + y =  180 \degree \\ (interior \:  \angle \: postulate) \\ 120 \degree   + y = 180 \degree  \\ y = 180 \degree  - 120 \degree  \\ y = 60 \degree \\  \\ z = 180 \degree  -( 60 + 60) \degree  \\ z = 180 \degree  -120 \degree   \\ z = 60 \degree

What is the length of AB?
makkiz [27]
The radius of the circle is given to be r = 14.5

Let the center be O. So OB is the radius = 14.5

We can draw a triangle as shown in the image below. We have a right angled triangle. We know the hypotenuse and the base, we need to find the perpendicular side. This can be done using the Pythagorean theorem.

So, we can write:

(14.5)^{2}=10^{2}+OA^{2} \\  \\ 
OA^{2}=110.25 \\  \\ 
OA=10.5

Thus, the measure of OA = 10.5

OB = OA + AB

14.5 = 10.5 + AB
⇒
AB = 4

-5 because you are adding -5 every time 

0= -2
-1 = -7
-2 = -12
-3 = -17
