The measure of two supplementary angles are x+10 and 2x-5. Find the values of x and then find the angles

astra-53 [7]

Answer:

68 1/3, 111 2/3

Step-by-step explanation:

The sum of two supplementary angles is 180°, so ...

(x +10) +(2x -5) = 180

3x +5 = 180 . . . . . collect terms

x +5/3 = 60 . . . . . divide by 3

x = 58 1/3 . . . . . . . subtract 5/3

The first angle is ...

x +10 = 58 1/3 +10 = 68 1/3

The second angle is ...

2x -5 = 2(58 1/3) -5 = 116 2/3 -5 = 111 2/3

The angles measure 68 1/3 and 111 2/3.

Image of parabola with a maximum value at (1, 9), y-intercept at (0, 8) and x-intercepts at (2, 0) and (4, 0).

natka813 [3]

Answer:

(a) 4 seconds

Step-by-step explanation:

The given point (4, 0) on the parabola tells you the answer to the question: the coin was in the air 4 seconds before its height is 0. It is no longer in the air at that point.

<em>Additional comment</em>

In order to match the rest of the problem statement, the first given x-intercept must be (-2, 0).
