Answer:
k
Step-by-step explanation:
I want to say 81°
Here's how I found that:
The angle 105° is on a straight line showing the outer obtuse angle. A straight line is 180°.
180-105=75.
Therefore that inner angle of the 105° is 75°.
We are also given the top angle of 24°.
All 3 angles of a triangle should add up to 180. So, we get the 75+24=99
180-99=81
Last angle should be 81°
When we have a negative exponent, we use the negative exponent property: a negative exponent with it’s base must be the reciprocal of the base and negative exponent, in order to make it a positive exponent.
Solving:
(-3)^-3/1
We made the base of -3 and exponent of -3 a fraction over 1, because we will need to take the reciprocal (flipped upside down fraction) of it.
1/(-3)^3
We now have a positive exponent. We took the reciprocal of (-3)^-3/1, so we just flipped the fraction upside down to 1/(-3)^3, which gave us a positive exponent.
1/(-3)^3 = 1/(-3)(-3)(-3) by the definition of an exponent (how many times a number multiplies itself).
Now , we just simply by multiplying -3 to itself 3 times.
1/-27 is the answer.
