Answer:
D.)
Step-by-step explanation:
Lowest point in the data is 12 and highest point in the data is 29 which is why the whiskers extend from 12 to 29. The line in the box is placed at 23 because this is the median. Lastly the box itself is extending from 17 to 28 because it represents the three quartiles. 17 being the first Quartile, 23 being the second Quartile (aka the median), and 28 being the third Quartile.
Answer: ∠ECB = 60°
Step-by-step explanation:
First, find the value of <em>x </em>by adding them up.
x + 3x + 2x = 6x
Since we know that all of the angles create a 180° angle, we can set up a proportion.
6x = 180°
To find the value of x, divide both sides by 6.
6x ÷ 6 = x
180 ÷ 6 = 30
So now the proportion is x = 30.
Now that we now x = 30, we can plug in 30 to the angle measures.
∠DCA = 30°
∠DCE = 90°
∠ECB = 60°
So angle ECB is 60°.
hope this helps!
The hypotenuse is always the longest side, and it is always opposite the right angle.
"Leg" is not a mathematical term. If it is being used to refer to one of the sides forming a right angle, the hypotenuse is not a "leg".
