Answer:
b = 2 cm
b = 10 cm
Step-by-step explanation:
Area of a Rectangle: A = lw
Area of a Triangle: A = 1/2bh
We are given area and length, so simply plug it in:
14 = 7w
w = 2 cm
We are given area and height, so simply plug it in:
30 = 1/2(6)(b)
30 = 3b
2 cm
10 cm
14/7 = 2
This helps to find because area of rectangle = bh or base times height.
A = 1/2 bh
30 = 1/2 b 6
b = 10
8%
Multiply 0.57 or 57% by 0.14 or 14% to get 0.0798 which you can round to 8%.
The expected values from the product of 2 marbles are 1,2,3,4,5,6,8,10,12,15,20
THe expected values are 1,2,3,4,5,6,8,10,12,15,20

The length of the wire is 76.19 m.
It is given that a guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.
It means base of the right angled triangle is 40 m.
The wire makes an angle of 58deg 20min with the ground.
1 degree = 60 min
Using this conversion convert the given angle in degree.
In a right angled triangle
Therefore the length of the wire is 76.19 m.
