Answer:
3 ft.
Step-by-step explanation:
When you imagine the sentence, it is a right angled triangle. In this case, it's a Pythagoras Theorem. The formula for it is:
a²(opposite) + b²(adjacent) = c²(hypotenuse)
The building is the opposite, the distance between the foot of the ladder and the building is the adjacent, while the ladder is the hypotenuse.
We have the measurements except for the adjacent. So it will be:
c² - a² = b²
5² - 4² = b²
25 - 16 = b²
9 = b²
√9 = b
b = 3 ft
The answer is 3 ft.
Oslo is colder than Copenhagen by 7 degrees. When finding the colder temperature below 0, the larger number with a minus sign in front is the colder temperature. For example -9degrees is colder than -2 degrees.
Hope this helps if possible could I pls have brainliest?
Answer:
a = 105 sorry thats all I know
Combine like terms on the right side:


Add 9 to both sides:

Divide both sides by 5 to get x by itself:

The value of x is
7.
