2 I think
because 180 times 2 is 360. And then it would be a full angle.
Answer:
The radius is 6
Step-by-step explanation:
Radius is half of diameter, so half of 12 is 6.
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
sin²Θ = 1 - cos²Θ , cos²Θ = 1 - sin²Θ
Consider the left side
(sinΘ + cosΘ)(1 - sinΘcosΘ) ← distribute
= sinΘ(1 - sinΘcosΘ) + cosΘ(1 - sinΘcosΘ)
= sinΘ - sin²ΘcosΘ + cosΘ - sinΘcos²Θ
= sinΘ - (1 - cos²Θ)cosΘ + cosΘ - sinΘ(1 - sin²Θ)
= sinΘ - cosΘ + cos³Θ + cosΘ - sinΘ + sin³Θ ← collect like terms
= sin³Θ + cos³Θ
= right side ⇒ proven
Answer: Choice B) SAS
=======================================================
Explanation:
The sides that have the double tickmarks are the same length. This forms one "S" of "SAS".
The square angles are 90 degree angles, or right angles. They are congruent. This forms the "A" of "SAS".
The overlapping sides are the same length, which forms the second "S" of "SAS".
The angle is between the two sides allowing us to use SAS. The order is important.
