Question

In a triangle ABC,angleB=35°,angleC=55° Write which of the following is true:
1)ACsquare= ABsquare+BCsquare
2)ABsquare= BCsquare+ACsquare
3)BCsquare= ABsquare+ACsquare

Answer 1

Answer:

BC sq = ABsq + ACsq

Step-by-step explanation:

since the total angle of a triangle is 180°

angleA =90°

therefore, BC is the sides opp. to angle A, which is the longest.

by applying the formula,

(hypotenuse)sq = (base)sq + (perpendicular)sq
