Question

in a straight angle triangle there are 3 edges if if B equal to 90 degree AC equal to 26 cm BC equal to 10 cm find AB please tell me fast​

Answer 1

Answer:

Given,

A Triangle with <B of 90°, AC = 26 cm and BC = 10 cm

Observation

We can see that this is a Right Angled Triangle

We can find AB through Pythagorean Theorem

a² + b² = c²

AB + BC = AC

Here, we should not be mistaken and take the values wrongly. If we take them wrong, we will obtain a wrong answer (in decimals)

a = ?

b = 10 cm

c = 26 cm

Finding

a² + 10² = 26²

a² + 100 = 676

(Transversing of 100 to RHS)

a² = 676 - 100

a² = 576

a = √576

a = 24

Conclusion

So, the length of AB is 24 cm
