Find the measure of angle x in the figure below: 56
51
72
O 35°
0 470
0 739
0 780

y = 73°

x = 35°

Step-by-step explanation:

1- getting the value of y:

We know that a straight angle has a measure of 180°.

We can note that:

The three angles 51° , 56° and y form a straight angle.

This means that:

51 + 56 + y = 180

107 + y = 180

y = 180 - 107

y = 73°

2- getting the value of x:

Now, in any triangle, the sum of the interior angles must be 180°.

In the given triangle we have:

an angle measuring 72°

an angle y measuring 73°

an angle x that we want to find

Therefore:

72 + 73 + x = 180

145 + x = 180

x = 180 - 145

x = 35°

Hope this helps :)

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
