Question

the angle measure (30-x)° and (125 + 2x)° of two angles are supplement of each other. Find the value of x​

Answer 1

Step-by-step explanation:

30 - X + 125 + 2x = 180 ( sum of supplementary angles are 180 )

X + 155 = 180

X = 180 -155

X = 25 °

Answer 2

Answer:

Question :-

the angle measure (30 - x)° and (125 + 2x)°

and both of the angels are supplement of each other

And Firstly here is a question = What does supplement stand for ?

Supplement means the sum of two angels is equal to 90° but both supplement and linear pair is different from each other. in linear pair there may be two or more than two angels and it is impor to be thr part of same line in linear pair but in supplement angle both two angles are part of different triangles

Now coming into your question

So , (30 - x) + (125 + 2x) = 180

= 30 - x + 125 + 2x = 180

= 155 + 2x - x = 180

= shifting 155 into RHS so the sign will also change

= x = 180 - 155 = 25 °

So finally your answer is 25°
