Trigonometry can be used to find angles and sides of simple triangles. If an 18-foot ladder touches a building 14 feet up the wall then the angle can be deduced by trigonometry. In this case, the ladder defines the hypotenuse (H) of the triangle and the wall defines the opposite (O) side of the triangle. Therefore we can use the equation theta=sin^-1(O/H) . This yields an angle of 51 degrees.

Step-by-step explanation:
E
working ;
(3x+2)^2
*Apply Perfect Square Formula : (a+b) =a^2+2ab+b^2
a = 3x,b = 2
(3x)^2 + 3x.2+2^2
finally Answer is:
= 9x^2 + 12x +4
Answer:
502m
Step-by-step explanation:
let x and y represent the length and breadth of rectangular meadow respectively.
Given,
Perimeter of the meadow =1004m
or,2(l+b)=1004m
or2(x+y)=1004m
orx+y=1004m/2
or,x+y=502m
i.e sum of length and breadth
Let the Volume of the first cube be V1
V1 = 2 * 2 * 2
= 8 cm*3
Let the Volume of the second cube be V2
V2 = 6 * 2 * 12
= 144 cm*3
Now, cube1 with volume of 8 cm*3 holds 468 grains of rice.
Thus, 1 cm*3 volume can hold 58.5 grains of rice ( 468 / 8 = 58.5)
Cube2 has volume of 144 cm*3.
Hence, it can hold 8424 grains of rice ( 144 * 58.5 = 8424)
