(b) (PQ)² + (PR)² = (QR)²

$\large\bold\color{tan}{\underbrace{Explanation}:-}$

Sum of all angles of a triangle is 180°. Here, the third angle P is:-

$180 - (47 + 43) = 180 - 90 = 90°$

So, the third angle is 90°. So, it is a right angled triangle which is right angled at P (Because, P is the unknown angle here). Then, always lines from point P will be squared to obtain the sum of square of other two sides:-

(PQ)² + (PR)² = (QR)² (b)

Answer 2

Answer:

Sum of all angles of a triangle is 180°. Here, the third angle P is:-

180 - (47 + 43) = 180 - 90 = 90°180−(47+43)=180−90=90°

So, the third angle is 90°. So, it is a right angled triangle which is right angled at P (Because, P is the unknown angle here). Then, always lines from point P will be squared to obtain the sum of square of other two sides:-

(PQ)² + (PR)² = (QR)² (b)
