answer this question very urgent please answer this maths problem fast

Answer 1

<bcd +<dce+<ecf=180°{ Straight angle,Linear pair}
=>2x+2x+30+x=180=
=> 5x+30=180
=> 5x = 150
=> x =30°
Thank u Hope it helped u!

Answer 2

Hey dear here is your answer!!!!!

___________________________

Since, BAC is a line. That means it form 180°.

This also means that all the angles over it form a linear pair of angles which sum up to 180°.

Now, according to question:-

∠BCD + ∠DCE + ∠ECA = 180°

Substitute the values of the angles:-

2x+ 2x + 30° + x = 180°

Add the like terms:-

5x + 30° = 180°

Transposing:-

5x = 150°

x = $\frac{150}{5}$

x = 30°

So, the angles are 60°, 90° and 30°.
