Answer:

20.19°

Step-by-step explanation:

Find the diagram to the question attached. We are to look for <CAB

Applying sine rule on ΔABC:

\frac{4.5}{sin15^0} = \frac{6}{sin

cross multiply

4.5 * sin

Hence the angle <CAB is 20.19°

A regular octagon has an apothem measuring 10 in. and a perimeter of 66.3 in. What is the area of the octagon, rounded to the ne
Lerok [7]

Answer:

332in^2

Step-by-step explanation:

The area of a regular polygon is calculated using the formula;

Area=\frac{1}{2}ap

where a is the apothem and p is the perimeter.

It was given that, the apothem is, a=10in. and the perimeter is p=66.3 in.

We substitute into the formula to obtain;

Area=\frac{1}{2}\times10\times66.3in^2

Area=331.5in^2

To the nearest square inch, we have;

Area=332in^2

Food costs are expected to rise 6% each month for the next year. Which series correctly depicts the cost (to the nearest cent) f
alexira [117]
For this case we have the following equation:
 y = 150 * (1.06) ^ t
 For the first month we have:
 y = 150 * (1.06) ^ 1
 y = 159 $
 For the second month we have:
 y = 150 * (1.06) ^ 2
 y = 168.54 $
 For the third month we have:
 y = 150 * (1.06) ^ 1
 y = 178.65 $
 Answer:
 
d. $ 159.00 + $ 168.54 + $ 178.65

Alana is writing a coordinate proof to show that the diagonals of a rectangle are congruent. She starts by assigning coordinates
tamaranim1 [39]
D(S,P) = √(0-0)^2 + √(b-0)^2
d(S,P) = √b^2
d(S,P) = b
so
SP = b

d(P, Q) = √(a-0)^2 + √(b-b)^2
d(P, Q) = √a^2
d(P, Q) = a
so
PQ = a 

SQ = c^2 = a^2 + b^2
SQ = √(a^2 + b^2)

answer
 the length of one of the diagonals of the rectangle is √(a^2 + b^2)
