Question

HELP ME ASAP PLEASE

Answer 1

Answer:

Radius AC=12

Step-by-step explanation:

AB is a tangent to circle c so the tangent AB is perpendicular to the radius at A.

Then triangle ABC is right triangle at A.

So by Pythagoras theorem,

CB^2=AB^2 + AC^2

37^2= 35^2 + AC ^2

1369=1225 + AC^2

AC^2= 1369-1225= 144

AC=radical AC^2 =radical 144=12

Hope this helps...

(Note: ^ means power)

Answer 2

Answer:

AC = 12

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2

AC ^2 + AB ^2 = CB^2

AC ^2 +35^2 = 37^2

AC ^2 +1225=1369

Subtract 1225

AC^2 = 1369-1225

AC ^2 =144

Take the square root of each side

AC = sqrt(144)

AC = 12
