Question

•Construct a right angled triangle ABC, right angled at B in which AB = 3 cm and BC = 4 cm Measure AC. ​

Answer 1

Answer:

Given,

ABC is a right angled triangle. It is right angled at B. AB = 3cm and BC = 4cm

To find:

Length of AC

Answer: 5cm = AC

Solution:

Refer to the image first.

Angle B = 90°

H= Hypotenuse

P= Perpendicular

B= BaseBy Pythagoras Thereom,

H² = P² + B²

Here, H = AC

B = BC

P = AB

So, AC² = AB² + BC²

AC² = 3² +4²

AC² = 9+16

AC² = 25 cm

AC = √25 cm

AC = 5 cm.

Therefore, the length of AC = 5cm.

Answer 2

Answer:

8 cm

Step-by-step explanation:

kyuki 4cm cb and 3Ab is equal Ac=8cm
