Use the pythagorean theorem or trig to find the length of the missing side, the hypotenuse.

You use the Pytha. theorem to find the length of the missing side or the hypotenuse

Step-by-step explanation:

a^2 + b^2 = c^2

c^2 = the hypotenuse

17

Step-by-step explanation:

Use the Pythagorean theorem to solve the problem.

The Pythagorean theorem states A^2 + B^2 = C^2

So, 15^2 (225) + 8^2 (64) = 289

Take the square root of 289. which is 17.

Hope this helps!

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
