Question

In∆ABC, angle ABC=90 AC=74BC=70 complete the following activity to find AB​

Answer 1

Step-by-step explanation:

We know that AC= 74,BC=70.

angle ABC=90 ( therefore it is a right angled triangle )

By the Pythagoras theorem,

(AC)^2 = ( AB )^2 + (BC)^2

74^2. =. AB^2 + 70^2

5476. =. AB^2 + 4900

AB^2. =. 5476 - 4900

AB^2. =. 576

AB. =. √576

therefore,

AB = 24
