Question

3. Find the length of the third side of a triangle whose two sides measure
18 cm and 14 cm?​

Answer 1

Answer:

माना, third side = x

two side of triangle = 18cm and 14 cm

हम जानते है कि triangle के तीनो कोणो का योग 180 डिग्री होता है

इसलिए, 18+14+x = 180

32+x = 180

x = 180-32

x = 148

अत: triangle of third side is 148 answer

Answer 2

Answer:

Here, is your answer

Step-by-step explanation:

first side = 18cm

second side = 14cm

By pythagoras theorem

( hypotenus) ^2 = (one side) ^2 + ( other side ) ^2

(18)^2 = (14) ^2 + (o.s)^2

324 = 196 + (o.s) ^2

(o.s) ^2 = 324 - 196

= 128

(o.s) = under root 128

•

• • The value of third side is

$\sqrt{128 }$
