Question

if the length of two sides of a triangle is 6cm and8 cm then its third side is 14 cm​

Answer 1

Step-by-step explanation:

In quadrilateral,

Sum of all angles = 360

Let the unknown angle be q

q + 70 + 55 + 136 = 360

q = 99

Now q + x = 180 (linear pair)

x = 81

136 + z = 180 ( linear pair)

z = 44

In traingle,

x + y + z = 180(angle sum property of traingle)

x + 125 = 180

x = 55
