There are 3
the number 5 number 3 and 2
<u>Answer:</u>
<u />
y=77+x
<u>Step-by-step explanation:</u>
The <em>Triangle Angle Sum Theorem</em> states that the sum of all of the angles in any triangle equals 180 degrees.
In the given triangle, two of the angles are already known. The third angle is 180 - y degrees, as all lines measure 180 degrees.
Therefore, the below equation can be put together.
77+x+180-y=180
77+x-y=0
x-y=-77
-y=-77-x
y=77+x
So, y in terms of x is ... y=77+x.
Hope this helps! Comment any questions.
