The measure of each angle is 159° and 21°.
<h3>
What are supplementary angles?</h3>
- When two straight lines or rays intersect at a single endpoint, an angle is created.
- The vertex of an angle is the location where two points come together.
- The Latin word "angulus," which means "corner," is where the word "angle" originates.
- Two angles are considered to be supplementary if their sums total 180 degrees.
- For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.
So, supplementary angles = 180
Then,
- 2x + 138 = 180
- 2x = 180 - 138
- 2x = 42
- x = 21
- 21 + 138 = 159
Therefore, the measure of each angle is 159° and 21°.

Answer:
<h3>Two of the sides of triangle KNM are the equal</h3>
Step-by-step explanation:
From the triangle KNM, we can see that two of the angles M K N and Angle N M K are the same. If two of the angles are equal this means that two of the sides of the triangles are also equal. This type of triangle is known as an ISOSCELES TRIANGLE.
An isosceles triangle is a triangle that has two of its angles and sides to be equal.

The rise or an increase in altitude is represented by positive sign and a decend or decrease in altitude is represented by negative sign.
First the helicopter descended 1200 feet. So the change in altitude will be -1200 feet.
Then the helicopter rose by 800 feet. So the change in altitude will be 800 feet.
Finally the helicopter descended by 450 feet. So the change in altitude will be -450 feet.
The net change in altitude will be the sum of all the above 3 changes.
Change in altitude = -1200 + 800 - 450 = -850 feet
The negative sign indicates a descend i.e. loss in altitude. So the net change in altitude was a loss of 850 feet.
