Question

There can only be one ______ angle in a right angled triangle.​

Answer 1

Step-by-step explanation:

(a + b)2 = a2 + 2ab + b2

(ii) (a – b)2 = a2 – 2ab + b2

(iii) a2 – b2 = (a + b) (a – b)

(iv) (a + b)3 = a3 + b3 + 3ab(a + b)

(v) (a – b)3 = a3 – b3 – 3ab(a – b)

(vi) a3 + b3 = (a + b) (a2 – ab + b2)

(vii) a3 – b3 = (a – b) (a2 + ab + b2)❤️
