Question

The angles of a triangle are x y and 40 degree the difference between two angles x and y is 30 degree find x and y

Answer 1

Answer:

Step-by-step explanation:

Here,

In a triangle sum of angles is is 180°

So, x + y + 40° = 180°

=> x + y = 140 -----> 1 equation

And given that x - y = 30°

x + y = 140

(-) x - y = 30

---------------

2y = 110

---------------

=> 《y = 55° 》

x + y = 140°

x = 140° - 55°

《 x = 85° 》
