Answer 1

Given that ∠B = 35o, ∠C = 55o Then, ∠A =? We know that sum of the angle of three sides of triangle is equal to 180o. = ∠A + ∠B + ∠C = 180o = ∠A + 35o + 55o = 180o = ∠A + 90o = 180o = ∠A = 180 – 90 = ∠A = 90o Also, we know that side opposite to the right angle is the hypotenuse. ∴ BC2 = AB2 + AC2 Hence, (iii) is trueRead more on Sarthaks.com - https://www.sarthaks.com/752726/in-a-abc-b-35and-c-55-write-which-of-the-following-is-true
