Answer:
Step-by-step explanation:
Given:
Required:
Solve for y (make y the subject of the formula)
SOLUTION:
Square both sides
Subtract both sides by x
Divide both sides by 2
Answer:
Step-by-step explanation:
If the ratio of the sides is 13:14:15, we can say that the length of each side is 13x, 14x and 15x.
Then, if the perimeter is 84 m, we have:
The length of each side is:
Now, to find the area of the field, we can use the following formula:
Where a, b and c are the sides and p is the semi perimeter:
So we have that:
Answer:
EA =
Step-by-step explanation:
Δ CEA and Δ CDB are similar by the AA postulate. Then the ratios of corresponding sides are in proportion , that is
=
( substitute values )
=
=
( cross- multiply )
9 EA = 150 ( divide both sides by 9 )
EA = =
