Determine the value of angle ECB<br><br><br> Please help me out!
ZanzabumX [31]

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!

Charlotte is working two summer jobs, making $21 per hour tutoring and $14 per hour clearing tables. Last week Charlotte worked
kramer

Answer: this is the answer please follow to the explanation

Step-by-step explanation:

21x + 14y = 168. X=2y

14y = -21x +168. 2y=x

14 divided by 14 on one side and

-21 + 168 divided by 14 on the other side

You should get...

Y= -3/2x +12

For part 2 where they want you to put the 2 numbers in, you should put the point they intercept which is (6,3).

Well, have a good day
