Question

find all the angles of a triangle i) triangle 5x 3x x

Answer 1

Answer:

given is 5x, 3x,x

To find the angles we find perimeter

and perimeter of∆ is sum of all sides

sum of ∆ is always of 180°

Therefore,

5x + 3x + x= 180

9x = 180

x= 180/9

x= 20

first side= x is 20

second side= 3x is 2×20= 60

third side= 5x is 5×20= 100
