Question

find the magnitude of the angle which is. 10 degree less than its supplementary angle
​

Answer 1

Answer:

x= 85

Step-by-step explanation:

let the first number be x

We know that sum of supplemnt angle is 180

Second number will be 180-x

So, 180-x is supplement of x

Given that number is 10 less than its supplement angle

So,

(180 - x) -10 = x

170 = 2x

x= 85

pls mark as brainliest answer

Answer 2

Let the angle be x
Hence ,
the supplementary angle= 180-x
Now, according to question,
180-x= x+10
170=2x
85=x
