(10 + 3x)° + (x - 30)° = 180°

(3x + x)° + (10 - 30)° = 180°

4x° - 20° = 180°

4x° = 180° + 20°

4x° = 200°

x° = 200/4

x° = 50°

So, the value of x is 50°

Hope it helps and is useful :)

What types of angle are 78 degrees and 144 degrees?

Alex17521 [72]

78- acute
144- obtuse

This is because anything less than 90 degrees is acute. Think of it as they are cute because they are tiny xD

=90 is right angel

And anything above 90 and below 360 is obtuse because it's fat xD
