Answer:
20 degrees
Step-by-step explanation:
A full angle is exactly 360 degrees, and if we were to cut it into 9, since 9 triangles (the two right traingles together) would be able to fit the nonagon, we would have first 40 degrees. Then the 40 degrees cut in half would be 20 degrees, since there are two right triangles present.

Answer:
74.6
Step-by-step explanation:
Tp find the average, add all the scores and divide by the number of scores.
56 + 90 + 67 + 82 + 78 = 373
Now divide 373 by 5.
373 / 5 = 74.6
Answer:
They are equal since they are both 90 degree angles.
Step-by-step explanation: Please brainliest? (Sorry if not correct.)
f(x) = 3x² + 2
3x² + 2 = 0
3x² = -2
3² + 2 = -2/3
F (-2/3) = 3 (-2/3) cross out the three + 2
= -2 + 2 = 0
Hope this helps a bit...
