The hypotenuse of a right triangle is 13cm long. the longer leg is 7 cm longer than the shorter leg. find the side lengths of the triangle.

is the second or third Pythagorean triple on the list, which gives us the answer directly.

But if we didn't know that, let x be the short leg:

Rejecting the negative root, x=5, other side 12, the Pythagorean triple we found.

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35

< 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
