which of the following correctly identifies angles that add up to 90 degrees and 80 dewgrees
None of the above.
This must not be so urgent.
so what is the answer
yea
To determine which angles add up to 90 degrees and 80 degrees, you can use the property that the sum of two complementary angles equals 90 degrees.
Complementary angles are two angles that add up to 90 degrees. Therefore, in order to identify the angles that add up to 90 degrees, we need to find pairs of angles whose sum equals 90 degrees.
Here are some possible combinations of angles that add up to 90 degrees:
1. 45 degrees + 45 degrees = 90 degrees
2. 60 degrees + 30 degrees = 90 degrees
3. 70 degrees + 20 degrees = 90 degrees
4. 80 degrees + 10 degrees = 90 degrees
Now, let's move on to finding angles that add up to 80 degrees. Unlike complementary angles, there is no specific term to describe angles that add up to 80 degrees. We need to find pairs of angles whose sum equals 80 degrees.
Here are some possible combinations of angles that add up to 80 degrees:
1. 40 degrees + 40 degrees = 80 degrees
2. 70 degrees + 10 degrees = 80 degrees
In summary, the angles that correctly identify those that add up to 90 degrees are 45 degrees + 45 degrees, 60 degrees + 30 degrees, 70 degrees + 20 degrees, and 80 degrees + 10 degrees. Meanwhile, the angles that add up to 80 degrees are 40 degrees + 40 degrees and 70 degrees + 10 degrees.
