Answer:
9.3 centimeters
Step-by-step explanation:
If the length of the third side of the triangle is c, then according to the Law of Cosines, c2 = 72 + 132 – 2(7)(13)(cos 44°). The value of c2 can be simplified to approximately 49 + 169 – 130.9198, or 87.0802, using a calculator. By taking the square root of 87.0802, the length of the third side of the triangle comes out to be approximately 9.3 centimeters.
Answer:
It invaluatesa to 1
Step-by-step explanation:
sin25 ∘cos65 ∘+cos25 ∘sin65 ∘=sin25
∘ sin(90 ∘−65 ∘)+cos25
∘cos(90 ∘−65 ∘ )
=sin25 ∘
sin25 ∘ +cos25 ∘cos25 ∘
=sin 2 25 ∘+cos 2 25 ∘=1

Answer:
first one: B and C
Second one: x=12, y=10 so the answer is B.
Step-by-step explanation:
First one: Irrational numbers are any numbers that go on forever in the decimal without ever repeating. Any square roots of numbers that aren't perfectly square, such as 4 and 9, are irrational. And anything with pi, or 
, is always irrational.
Second one: 144 and 100 are perfect squares, meaning it can be created by multiplying the same number by itself, in this case 12 and 10. Subtract those and you get 2.
