Angle x and angle y are complementary. Angle x is supplementary to a 128 degree angle. What are the measures of angle x and angl
alexdok [17]

The measurement of angle x is 52° and y is 38°

Step-by-step explanation:

Let us define supplementary and complementary angles first.

Supplementary angles is pair of angles whose sum is 180°

While complementary angles sum up to 90°

Given

That x and y are complementary and x is supplementary to 128.

This means that sum of x and 128 is 180°

So,

x+128 = 180\\x = 180-128\\x = 52

So,

x = 52°

It is also given that x and y are complementary which means that

x+y = 90\\52+y = 90\\y = 90-52\\y = 38

Hence,

The measurement of angle x is 52° and y is 38°

Keywords: Supplementary angles, complementary angles

How to find missing angle of a right triangle given 2 sides
tekilochka [14]

Answer:

As a rule of thumb, if you know only the two shorter side, their ratio is the tangent of the angle opposed to the side you use as a numerator.

If you know one side and the hypotenuse, the ratio side/hypotenuse is either the sine of the opposite angle, or the cosine of the adjacent angle.
