Answer:
x = 7
Step-by-step explanation:
( x +16)° = (4x - 5)°
x + 16 = 4x - x
16 + 5 = 4x - x
21 = 3x
7= x
hence, x =7
● Answer:
~~ 15 weeks
● Step-by-step explanation:
1 week = 7 days = 7×24hours = 168 hours
2500 hours ÷ 168 hours = 14.88 hours
~~ 15 weeks
2 cm = 8 feet.
4 / 2 = 2. 8 * 2 = 16. 16 feet in width.
Now, the length:
6 / 2 = 3. 8 * 3 = 24. 24 feet in length.
The actual dimensions are 16 feet in width and 24 feet in length.

any sum of two sides are bigger than the third side
Since it's a right triangle you can use the Pythagorean theorem or Trig (Soh Cah Toa).
I'll just use the Pythagorean theorem : a² + b² = c²
a = 9
b = x
c = 18
9² + x² = 18²
81 + x² = 324
x² = 324 - 81
x² = 243
x = √(243)
factor 243 to find a perfect square
x = √(3*81)
x = 9√(3)<u />
