In a triangle ABC, It is given that AB = 1 cm, BC = 2021 cm and AC = a cm, where a is an integer. Determine the value of a.1 point(A) a can be any positive integer.(B) 2021(C) 2020(D) 2023​

Answer»

ANSWER:

B) 2021

Step-by-step explanation:

Consider ️ ABC is a RIGHT angle triangle.

Where angle ABC = 90°

Using Pythagoras THEOREM

AB² + BC² = AC²

(1)² + (2021)² = AC²

1 + 4084441 = AC²

AC² = 408442

AC = 2021.0004

I.e. AC = 2021 cm
