Andrew can reach a maximum of
high up the wall.
The right-angled triangle formed can be solved using the
ratio. that is

where
is the distance from the foot of the wall to the tip of the ladder where it rests on the wall. Substituting, and solving for
, we get

Since Andrew can reach an extra
above the point where the ladder rests against the wall, the maximum height Andrew can paint is

x=8+sqrt-8/12, x=8-sqrt-8/12
I think...
Answer:
x(x + 8)(x - 8)
Step-by-step explanation:
Given
x³ - 64x ← factor out x from each term
= x(x² - 64) ← x² - 64 is a difference of squares
= x(x + 8)(x - 8) ← in factored form
Answer:
126°
Step-by-step explanation:
the total max percent can be 100%
OR
The total value of the pie is 100%
that means all sectors must add upto 100
=> x + x + 21 + 9 = 100
=> 2x + 30 = 100
=> 2x = 70
=> x = 35
therefore, the two large sectors which are both equal to x each represents 35% of the whole.
<u>Angle subtended by one of those large sectors</u> :-


therfore, the central angle of the big sector is<u> 126°</u>
