We first approach this problem by illustrating the situation. Refer to the diagram attached.
From the diagram, we can clearly see that we need to simply solve for the length marked x in order to find the distance between the foot of the ladder to the base of the wall.
Remember SOHCAHTOA. We can apply here the concept of cosine since we have the angle. Incorporationg x into the equation, we can simply make use of the relation cosine 72° = adjacent/hypotenuse.


ANSWER: The distance between the foot of the ladder and the base of the wall is 4.6 feet.
Answer:
x^2 + x + 2 = 0.
Step-by-step explanation:
The discriminant b^2 - 4ac is < 0 for complex roots.
So we can choose appropriate values for a, b and c.
Let b = 1, a = 1 and c = 2 so b^2 - 4ac = 1 - 4*1*2 = -7.
So our equation is:
x^2 + x + 2 = 0.
Answer: (first half) Dylan= $10.5 per hour
Angela$10 per hour
(second half) No because they have different rate as the one before
Step-by-step explanation:
step one : divied how much money they make by the number of hours
Dylan
$336/32 hours = $10.5 per hour
Angela
$420/42 hours = $10 per hour
Step two: multiply the answer you got for Dylan by 25 hours and Angela by 42
Dylan
10.5 (25) = $262.5
Angela
10 (42)= 420
(Rates)
Dylan rate before = $336
Rate after solving = $262.5
Angela rate before = $420
Rate after solving = $420
i hope this helps ;)
So 7=7/1
to put a 9 in the bottom and make the fraction stay the same, multiply it by 1
or 9/9 since 9/9=1 so
7/1 times 9/9=(7 times 9)/(1 times 9)=63/9
answe ris 63/9
