12/x =30%/100
cross multiply and divide by the percent
thats 40
12 is 30% of 40
Step-by-step explanation:
The image is attached below.
Given AB = 9
BC = x
AC = y = 18
Note that the given triangle is a right angled triangle.
We know that Pythagoras theorem states that in a right angle hypotenuse is equal to the sum of the squares of other two sides.
Using Pythagoras thereom,
Taking square root on both sides,
Hence, the value of x is .
An angle of pi/2 radians can be transformed into degrees
using the conversion formula (180/pi):
φ =
(pi / 2) * (180 / pi) = 90˚
Therefore an angle of pi/2 rad is just equivalent to 90˚.
Since 90<span>˚ is located on the y-axis, therefore the horizontal component x is
zero. So cosine of this angle is zero.</span>
