Question

(B) Solve the following sub-questions. (Any two)
(1) In AABC, ZABC is a right angle. I(AC) = 41, 1(BC) = 40, then l(AB) = ?​

Answer 1

Answer:

AB=9cm

Step-by-step explanation:

In Triangle ABC is a right angle.

Hypotenuse(AC)=41 cm

Base(BC)=40cm

Perpendicular(AB)=$\sqrt {AC^{2} - BC^2}$=$\sqrt{41*41-40*40}$=$\sqrt{1681-1600}$=$\sqrt{81}$=9cm
