1.	If two sides of a right angled triangle are 20cm and 21cm, then hypotenuse = ______cm
Answer» ANSWER: hypotenuse = 29.68cm Step-by-step explanation: Let Triangle ABC is a right ANGLE triangle. AB= 20cm, BC = 21cm and AC = ? By Pythagoras THEOREM (AC)^2 = (AB)^2 + (BC)^2 (AC)^2 = (20)^2 + (21)^2 (AC)^2 = 400 + 441 (AC)^2 = 841 AC = 29.68 (Taking square root) Therefore, hypotenuse is 29.68cm

If two sides of a right angled triangle are 20cm and 21cm, then hypotenuse = ______cm

Answer»

ANSWER:

hypotenuse = 29.68cm

Step-by-step explanation:

Let Triangle ABC is a right ANGLE triangle.

AB= 20cm, BC = 21cm and AC = ?

By Pythagoras THEOREM

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

(AC)^2 = (20)^2 + (21)^2

(AC)^2 = 400 + 441

(AC)^2 = 841

AC = 29.68 (Taking square root)

Therefore, hypotenuse is 29.68cm
