An exterior angle of a triangle is 180 degrees is never true. The simple reason behind this logic is that 180 degrees means a straight line and it is not possible for a straight line to create an exterior angle of a triangle. I hope that this answer will come to your help.
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:
1/4
Step-by-step explanation:
Rebecka already chose a retriever, so the puppies left for Aaron to pick are:
2 poodles
2 terriers
1 retriever
Total: 4
Number of retrievers left after Rebecka's pick: 1
p(Aaron picks retriever) = 1/4
Answer:
x=16 and y=9
Step-by-step explanation:
2y+30=3y+21[Diagonals of parallelogram are equal]
30-21=3y-2y
y=9
3y=2x-5[Diagonals of parallelogram are equal]
3×9=2x-5
27=2x-5
2x=27+5
x=32/2=16
