Determine the values of 𝑥 and
𝑦.
We begin by noticing that the two
angles with measures 62 degrees and 𝑥 degrees form a right angle. This means that they are
complementary angles as complementary angles sum to 90 degrees. We can write this as an
equation. 𝑥 degrees plus 62 degrees is equal
to 90 degrees. And since all the angles have the
same unit, 𝑥 plus 62 is equal to 90. We can then subtract 62 from both
sides of the equation. And this means that 𝑥 is equal to
28.
In order to determine the value of
𝑦, we note that all four angles lie on a straight line. The angle of measure 𝑦 degrees
combines with the angle that is the sum of 𝑥 degrees, 62 degrees, and 37 degrees to
make a straight angle. In other words, these angles are
supplementary since supplementary angles sum to 180 degrees. We have the equation 𝑦 degrees
plus 𝑥 degrees plus 62 degrees plus 37 degrees is equal to 180 degrees. And since 𝑥 is equal to 28, this
simplifies as shown. Adding 28, 62, and 37 gives us
127. So our equation becomes 𝑦 plus 127
is equal to 180. We can then subtract 127 from both
sides, giving us 𝑦 is equal to 53. The values of 𝑥 and 𝑦 are 28 and
53, respectively.
