The value of 3ab+5b-5 is 18
Answer:
x + 49 + 28 = 180
Step-by-step explanation:
The angles on a straight line with x° are 28° and 49° respectively, side by side with x°. This is because, vertical angles are equal. Therefore, the angle vertically opposite 28° and 49° are equal to 28° and 49° respectively.
Therefore, since angles on a straight line is 180°, thus:
x + 49 + 28 = 180
Pretty sure its B but if im wrong please dont be mad.
It is rational because any number that can be represented in a fraction is rational. 4/33 is a fraction, so it is rational.
