Question

Find the unknown length x in the following figures:​

Answer 1

Answer:

5

Step-by-step explanation:

Pythagoras Theorem states that a² + b² = c² (c being the hypotenuse)

3²+4²=x²

⇒ 25 = x²

⇒ √25 = √x²

⇒ x = 5

Answer 2

Answer:

X = 5 CM

Step-by-step explanation:

AS GIVEN IN THE FIGURE

THIS IS A RIGHT ANGLED TRIANGLE

THEN,

BY PYTHAGORAS THEOREM

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

(X)^2 = (4)^2 + (3)^2

(X)^2 = 16 + 9

(X)^2 = 25

X = √25

X = 5

HENCE X = 5 CM
