Answer:

-3n^3 - 2n^2 + 4.

Step-by-step explanation:

(3-7n^2+3n^3)-(6n^3-1-5n^2)

First distribute the negative over the second parentheses:

= 3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2

Now simplify like terms:

= -3n^3 - 2n^2 + 4 (answer).

Simplify

3 - 7n^2 + 3n^3 - (6n^3 - 1 - 5n^2)

Simplify brackets

3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2

Collect like terms

(3 + 10) + (-7n^2 + 5n^2) + (3n^3 - 6n^3)

Simplify

Answer:

The angle is 50 degrees.

Step-by-step explanation:

You'll see, the angle that is on the left of the 70° angle has to be 110°, because a straight line has 180°.

Now, the inner angles of a triangle have to sum 180°. So if the lower angle is 110° (because you just calculated it), and the upper angle is 20°, the third angle is:

180° = 110° + 20° + x

180° = 130° + x

180° - 130° = x

50° = x

Now this third angle is on the bottom left part of the triagle, and it's 50°. It also opposite to the angle 1, which is the one you want to calculate. Because they are opposites, they are identical, meaning that they both are 50°. This is due to a geometrical rule.
