neither, since the gradients are not the same, as well as the c value
Step-by-step explanation:
The answer is 90
20%of 99=18
Step-by-step explanation:
multiple the power and real number
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
