Answer:
16
Step-by-step explanation:
To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.
2/10 = x/5
Now, we can use cross products to simplify this proportion. Cross products sets the products of the numerator and denominator of separate fractions equal to one another. It results in the equation:
(5)(2) = (10)(x)
Let's multiply out these numbers to further simplify the equation.
10 = 10x
Finally, we have to divide both sides by 10, to get our variable x alone
x = 1
Therefore, 2 tenths is equal to 1 fifth.
= 4 = x²
x = Answer: Length= 11 , Brteadth = 2
Step-by-step explanation: Let the breadth of the rectangle be x
length = 9 + x
area = 36 cm²
A.T.Q
36cm² = 9x*x
36 = 9x²
36/9 = 4 = x²
x = root of 4
x= 2
Therefore , breadth of rectangle is 3cm and length is 12 cm
verification:
l*b = 12*3 = 36cm²
In the triangle XYB
cos(x)=XY/XB
in the triangle AYZ
cos(z)=YZ/AZ
we know that
cos(x)=cos(z) and XY=YZ
therefore
XY/XB=YZ/AZ-------------- > (XY/YZ)=(XB/AZ) remember that XY=YZ
1=(XB/AZ)---------- > XB=AZ---------- > the statement was proved
