Answer:
b. They can both be 90 degree angles
c. Acute angles are by definition 90 degrees, and acute is less than but not equal to 90 degrees
d. should be always
e. should be never (explanation: they have to be adjacent to be supplementary, and vertical angles are never adjacent)
Step-by-step explanation:

First, I would multiply the last two fractions because they're smaller and easier to work with:

Now that we've simplified it, we could multiply these terms and simplify. An easier method, however, would be to cancel out any common factors among the numerators and denominators before multiplying:

We can now multiply these terms:

The <span>product of 8/15, 6/5, and 1/3 is B, 16/75.</span>
Answer:
x = -35
Step-by-step explanation:
multiply both sides by 5
5x/5 = 5(-7)
simplify
x = -35
588, (16-4/2)= 14
(14) square 2= 196
196•3= 588
