The age of Sydney is 25 years old

<u>Solution:</u>

Given that Devaughn is 7 years older than Sydney

The sum of their ages is 57

Let the age of Sydney be "x"

Then according to given information,

Age of Devaughn = x + 7

Now, Sum of Sydney age and Devaughn age = 57

Substituting the values we get,

x + x + 7 = 57

2x + 7 = 57

2x = 57 - 7

2x = 50

x = 25

"x" represents age of Sydney. Hence Sydney's age is 25 years old

25.
25 + 32 = 57
Brainliest maybe? Trying to get to next rank. Sorry to ask.

Can you draw trapezoid three right angles

Hunter-Best [27]

Its impossible to draw a trapezoid with just three right angles.

a trapezoid has 4 sides, which means all the angles inside the trapezoid must add up to 360 degrees.

if you have just 3 right angles (90x3), you already use up 270 degrees. Leaving you with just 90 degrees left, which is also a right angle. That means, there has to be four, if you have at least 3.

12/5 is the answer because if you use the help of "SohCahToa" you find that 12 is the opposite side of angle A and 5 is the adjacent angle

Suppose a second player standing at (90,40) misses the ball, turns around and runs on a path parallel to the baseballs path. Wha

hoa [83]

Answer:

y = (1/3)x + 10.

Step-by-step explanation:

The path of the baseball is shown in the image below. We can see that the baseball passes through the point (0, 0) and (60, 20). The equation of the baseball path is gotten using the formula:

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{20-0}{60-0} (x-0)\\\\y=\frac{1}{3}x$

The equation of a straight line is given as y = mx + b, where m is the slope, b is the y intercept

The slope of the baseball path is 1/3

The second player is at (90, 40) and runs parallel to the baseball path.

If two lines are parallel then they have the same slope.

Since the player moves parallel to the baseball path, the slope would also be 1/3. The equation of the players path is gotten using:

$y-y_1=m(x-x_1)\\\\y-40=\frac{1}{3}(x-90)\\\\y= \frac{1}{3}x - 30+40\\\\y=\frac{1}{3}x+10$
