<u>Answer</u>
12
<u>Explanation</u>
Cosine is the ratio of adjacent to hypotenuse.
So, in this case b is the adjacent and 13 is the hypotenuse.
cos22.6 = b/13
b = 13×cos22.6
= 13×0.923879532
=12.010
To the nearest whole number the answer is 12.
Answer:
i think it is increase by 28%
Step-by-step explanation:
-----------------------------------------------------------------------------------------------------
The perimeter is 4/3x(3), or 12/3x.
The area is (2x+2)^2
Therefore, we must solve the equation
4x^2+4x+1= 0
This eventually factors to x = -0.5.
10^2 = 10 × 10
10^3 = 10 × 10 × 10 = 1000
10^4 = 10 × 10 × 10 × 10
