Let unknown number be x
3x + 5 = 65
3x = 60
x = 20
Therefore, unknown number is 20.
Cosine = adjacent / hypotenuse
cos (49)= x/27
27 * cos(49) = x
27 * 0.656 = x
x = 17.7
Answer:
Perimeter = 44cm
we know that square has 4 sides which are same
so perimeter means sum of all 4 sides
4 × s = 44cm
s = 11cm
Each side will be of 11cm.
Now area of square is Square of its side length.
so area = 11 × 11 = 121 cm^2
Answer:
10, 22, 48.4, 106.48, 234.256
Step-by-step explanation:
The first term is already given it is 10.
The second term is the first term times 2.2.
10×2.2=22
The second term is 22.
The third term is the second term times 2.2.
22×2.2=48.4
The third term is 48.4.
The fourth term is the third term times 2.2.
48.4×2.2=106.48
The fourth term is 106.48.
The fifth term is the fourth term times 2.2.
106.48×2.2=234.256
The fifth term is 234.256.
