Question

in figure given below triangle ABC congruence tu triangle d e f such that AB is equal to AC is equal to DF and BC is equal to find X and Y on the basis of data provided in the diagram​

Answer 1

Step-by-step explanation:

Let the angle A be x

We know, sum of angles of a triangle = 180°

Therefore, x + (x - 5) + 25 = 180

x + (x - 5) + 25 = 180 =) 2x - 5 + 25 = 180

x + (x - 5) + 25 = 180 =) 2x - 5 + 25 = 180=) 2x = 180 + 5 - 25

x + (x - 5) + 25 = 180 =) 2x - 5 + 25 = 180=) 2x = 180 + 5 - 25=) 2x = 160

x + (x - 5) + 25 = 180 =) 2x - 5 + 25 = 180=) 2x = 180 + 5 - 25=) 2x = 160=) x = 160/2

x + (x - 5) + 25 = 180 =) 2x - 5 + 25 = 180=) 2x = 180 + 5 - 25=) 2x = 160=) x = 160/2=) x = 80°
