Answer:
x = 2.25 (Approximately)
Step-by-step explanation:
4 + 3x^4 = 81
4 - 4 + 3x^4 = 81 - 4
3x^4 = 77
(3x^4)/3 = 77/3
x^4 = 25.67 (Approximately)
x = 2.25 (Approximately)
The longest side = x
the second side is half the longest side = (1/2)x
the third side is 12 feet less than the longest side = x-12
The perimeter (the sum of all sides) is 53.
The lengths of the sides are 13, 14 and 26 feet.
Answer:
Step-by-step explanation:
ABC is the sum of the angles CBD and ABD. So:
Substitute them for their equations:
Solve for x. Combine like terms on the right:
Add 11x to both sides:
Subtract 241 from both sides:
Divide both sides by 4:
The value of x is 9.
And we're done!
