Answer:
34 units
Step-by-step explanation:
The perimeter of a triangle is given by the sum of the lengths of its three sides.
So if the perimeter is 68 units and the sides measure x, 2x and 3x, we have that:
x + 2x + 3x = 68
6x = 68
x = 68/6 units
Now with the value of x we can find the length of EO:
EO = 3x
EO = 3 * (68/6)
EO = 68/2 = 34 units
Answer:
x = - 6
Step-by-step explanation:
Given
x + 5 = 1 ( subtract 5 from both sides )
x = - 4
Multiply both sides by 3 to clear the fraction
2x = - 12 ( divide both sides by 2 )
x = - 6
Answer:
7.28 m
Explanation:
Use the Pythagorean Theorem. The length of the ladder is the hypotenuse.
a^2 + b^2 = c^2
a = 2, b = 7, c = ?
Plug in the values into the equation.
2^2 + 7^2 = c^2
4 + 49 = c^2
Square root both sides to get c = 7.28
