Answer:

x° = 54°

Step-by-step explanation:

The angle where the diameter meets the tangent line is a 90° angle, so the angle x° is complementary to the angle 36°. (Thus the sum of angles in the triangle is 180°.)

x = 90 -36 = 54

How can the additive inverse be used to evaluate the problem below? –3 – (–6)
Because 3 + (–6) is an equivalent expression, the answer is –3.
Because 3 + (–6) is an equivalent expression, the answer is 3.
Because –3 + 6 is an equivalent expression, the answer is –3.
Because –3 + 6 is an equivalent expression, the answer is 3.

Answers

Answer: Because –3 + 6 is an equivalent expression, the answer is 3.

Step-by-step explanation:

We know that the additive inverse property says that the additive inverse of any arbitrary number x is a number which when added to x results 0.

For any real number, it generally reverses its sign.

i.e. Additive inverse of x = -x such that x+(-x)=x-x=0

The given problem : -3-(-6)

Using additive inverse property, the additive inverse of-6=6

\Rightarrow\ -3-(-6)=-3+6\n=6+(-3)...............................\text{[Commutative property]}\n=6-3\n=3
addative invesre means adding the invese is same as subtracting the other (???)
confusing

-3-(-6)=-3+6=3
