A quadrilateral has angle measures of 41 52 and 54 which is the measure of the last angle

nexus9112 [7]

Answer:

213 degrees

Step-by-step explanation:

A quadrilateral has an internal measurement of angles of 360 degrees. Given that we have 3 measures of the angles, we simply need to find the 4th. This can be accomplished with the following equation:

x + 52 + 54 + 41 = 360

x + 52 + 95 = 360

x + 147 = 360

x = 213

Hence, the measure of the final angle is 213 degrees.

Cheers.

Problem 2.9 a runner completes the 200-meter dash with a time of 20.19 seconds. part a what was the runner's average speed in me

Elina [12.6K]

Answer:

Average speed = 9.91 m/s

Explanation :

Total distance covered by a runner = 200 m

Time taken to complete this distance = 20.19 sec

We need to find the average of runner speed in meter/sec

We use the speed, distance, time formula

$speed = \frac{distance}{time}$

speed = $\frac{200}{20.19}$

Average speed = 9.91 m/s

that's the final answer.

I hope it will help you.
