42 degrees
Step-by-step explanation:
Answer:
cos(2sin−1x)=1−2x2
Step-by-step explanation:
et sin−1x=θ , so that, x=sinθ,|x|≤1,θ∈[−π2,π2].
Answer:
42.5 units²
Explenation:
The area of the square on the left is 5×5=25.
At the top you do 12-5=7 to find the length of the tringle.
Than it is 7×5=35 than this divided by two, so 17.5.
You add both areas 25+17.5=42.5
Answer:
Suppose that logb b = x.
bx = b (Use the definition of a logarithm.)
bx = b1
x = 1 (Use the common base property.)
So, logb b = 1.
