Answer:
acute
Step-by-step explanation:
straight is just a straight line, 180 degrees perhaps
right is exactly 90 degrees
obtuse is over 90 degrees
It would be 21070
In standard form, 20000+1000+70
( c^2 )^3 = 64 <=>( c^2 )^3 = 4^3 <=> c^2 = 4 <=> c = 2 or c = -2.
The answer is A, if the two values are the same because equivalent means equal to one another, or the same.
Hope this helps!
