The length of the sides of the shape.
Step-by-step explanation:
Answer:
<h2>
Angle X; 39</h2><h2>
Angle Y; 129</h2>
Step-by-step explanation:
180-90
90
This gives us the measurement of 51+x.
90-51
39
This is x as well as the angle that is across from it.
x+90=y
39+90=129
y=129.
to find the last angle, we add 90 to 51. This gives us 141.
So, now we add up all of the angles to double check everything. If they all add up to 360 then we are correct.
39+39+51+90+141=
360.
This means that we have solved everything correctly and that these are the correct answers.
I know that this is really confusing but the answers that you need are at the top so hopefully this helped!
I am confident that the answer is C. 53.7
