Answer:
Equilateral, acute
Step-by-step explanation:
Equilateral triangles have all sides the same length (all sides are 4 ft in this triangle, so it is equilateral).
Acute triangles have no angles that are greater than or equal to 90 degrees (all angles are 60, which is less than 90, so it is acute).
The measure of the third angle would be 159 degrees
Answer:
-195 degrees
Step-by-step explanation:
we can subtract 360 from 165 to find the negative coterminal angle.
165-360=-195
Answer:
h(-9) = -107
Step-by-step explanation:
h(-9) = 4(-9)2 + 3(-9) - 8 = -107
