Two angles measure (30°-a) and (125°-a).if each one is the supplement of the other then find the value of a.
Akshaysingh11:

Given that the angles are supplementary ( Sum of them equals a straight angle.
Now,
=> (30-a)+(125-a) = 180
=> 30-a + 125 -a = 180
=> 155 -2a = 180
=> -2a = 180-55
=> -2a = 25
=> a = -12.5
Now,
=> (30-a)+(125-a) = 180
=> 30-a + 125 -a = 180
=> 155 -2a = 180
=> -2a = 180-55
=> -2a = 25
=> a = -12.5

Hello...
(30-a)+(125-a) = 180
30-a + 125 -a = 180
155 -2a = 180
-2a = 180-55
-2a = 25
a = -12.5
(30-a)+(125-a) = 180
30-a + 125 -a = 180
155 -2a = 180
-2a = 180-55
-2a = 25
a = -12.5
180
sorry this is correct
sorry this is correct
correct
see what you had written in 4th line
Thanks to all of you
Answer is correct, but 4th step is definitely wrong
