Question

In the figure, find the value of x , if triangle ABC is right angled triangle. ​

Answer 1

Answer:

17cm

Step-by-step explanation:

from pythagorean theorem,

(AB)²+(BC)²=(CA)²

(8)²+(15)²=(AC)²

64+225=(AC)²

√289=AC,AC=17cm

Answer 2

Question :

In the given figure, find the value of x, if ∆ABC is right angled triangle.

Solution :

∆ABC is right angled triangle.

Given :

AB {Perpendicular(P)} = 8cm

BC {Base(B)} = 15cm

To Find :

AC {Hypotenuse(H)} = ?

Steps :

As we know in Right Angled Triangle,

P² + B² = H²

So, in ∆ABC

8² + 15² = x²

(8×8) + (15×15) = x²

64 + 225 = x²

x² = 289

x = √289

x = 17cm
