We just use the sinus rule to calculate this
a / sin alpha = b / sin beta
Alpha is the 90 degree angle from the wall to the floor
beta is the angle from the top of the ladder to the wall,
wich is 90 degrees - 75 degrees (triangle has 180 degrees angles, one is 90 degrees), so beta = 15 degrees
14 foot / sin 90 = b / sin 15
sin 90 = 1
we move the sin15 over to the other side
14 foot x sin 15 = b
b = 3.62 foot
Answer:
no
Step-by-step explanation:
The length of any side of a triangle cannot exceed the sum of the lengths of the other two sides. ... Therefore, if two sides have length 6 cm and 9 cm, the third side has length between 9–6 = 3 cm and 9+6 = 15 cm.

the composite function from K to F :
(F o C) (x) = 9/5 (x - 273.15) + 32 (option D)
Answer:
$467.05
Step-by-step explanation:
The price is $562
First, 20% off of that:
562 - 20% of 562 = 562 - 0.2(562) = $449.60
Second, he has to pay 6% tax on this amount, so:
6% = 6/100 = 0.06
449.60 + 0.06*449.60 = $476.58
He won't be paying this amount, because paying through credit card will give him 2% discount on this, so:
476.58 - 0.02(476.58) = $467.05
