Is a triangle with side lenghts 18, 12, and 22 a right triangle?

No

Step-by-step explanation:

Pythagorean Theorem goes with a right triangle, the formula is a^2+b^2=c^2.

Let's try this out with your values.

(18*18)+(12*12) = 468

If this is true than c^2 is 468

c^2 or (22*22) is 484 is this is not a right triangle.

i can answer this question sweetie!

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
