Answer:

x=20, y=70

Step-by-step explanation:

∠40°+∠adjacent to it =180°

∠adjacent= 180-40=140°

we see that 2 of the sides of one of the small triangles are congruent so that triangle is isoscel so the base angles are congruent as well

because sum of angles in a triangle has to be 180,

140 +x+x=180 so x=20°

from the right triange we see thhat y +90+20 =180 because sum of angle in a triangle has to be 180 so y=70

Example:
To find the average for 10,18 and 13.

We just have add the following numbers and divided them by how many numbers you added.

Solution:
10 + 18 + 13 = 41
41 / 3 = 13.67 or 14
Then the average score is 14.

Jessica ran on the track team at her school. She finished the 200-meter race in 54 seconds. What was jessica's average speed,in

Scrat [10]

Answer:

$v =\frac{x}{t}$

Where x represent the distance and t the time if we replace the info given we got:

$v = \frac{200m}{54 s} =3.704 \frac{m}{s}$

Then the average speed for this case in m/s is 3.704 for the 200 meter race

Step-by-step explanation:

The problem provides for this case the amount of distance travelled by Jessica in a given time. And we know that travels 200m in 54 seconds.

We want to find the average speed and we can use the following formula:

$v =\frac{x}{t}$

Where x represent the distance and t the time if we replace the info given we got:

$v = \frac{200m}{54 s} =3.704 \frac{m}{s}$

Then the average speed for this case in m/s is 3.704 for the 200 meter race
