M= 33
Since degrees equal with the other one across from them.
N= 57
The reason why is because a right angle equals 90 degrees and 90-33 is 57.

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°.

Answer:
99 and 100.
Step-by-step explanation:
Let's say the lower number is x. This means that the bigger number would be x+1
x+x+1=199
Simplify
2x+1=199
Subtract 1 on each side of the equation to isolate 2x:
2x=198
Divide
x=99
Let's put this to the test! The lower number(x) is 99, and the bigger number(x+1) would be 100. The total is 199.
Happy learning!
