Question

sum of the two angels are equal to the third angle.and different between the two angle is 50 find third angle?​

Answer 1

Answer:

$a \: \: \: \: 90 - 50 = 40 \\ \\ 90 + 50 + 40 = 180 \\ \\ 180 - 50 - 40 = 90ans$

Answer 2

As we know that a straight line has angle of 180
Suppose (x+50) is the first angle and (y) is the second angle
As we know that difference between them is =50 we can right
50+x-y=50
Where value of x and y is 65 because 180-50 =130 we have - the 50 because we have already added it to x
So as the line has 180 degrees so only 130 degrees will be left
So only by putting x and y 65 we can get answer 50
Know equation 2 is
Sum of angle x and y is =3rd angle
As we know now that angle x and y are 65 degrees so
65+65=130
So 3rd angle will be 130degree
