Answer:

<u>The correct answer is letter c.</u>
Step-by-step explanation:
The area equation of a triangle is given by:
(1)
Where:
b is the base
h is the height
Let's find first the angle MJK (α), using the tangent definition.



Now, if α = 37° then β (angle JLK) must be:


Now, we can find the distance ML using again the tangent definition:



The base of the triangle LKJ will be:

Therefore, using equation (1) the area of △LKJ will be:


The correct answer is c.
I hope it helps you!
Answer:
l(l - 2) = 168
Step-by-step explanation:
Let w = width
Let l = length
Let A = area
w = l - 2
A = l * w
also, A = 168
equating the two values of A
l * w = 168
l * (l - 2) = 168
l^2 - 2l = 168
l(l - 2) = 168
<span>perimeter of a rectangular rug is 30 yd
P= L+L+W+W
</span><span>P= 9+9+W+W
P= 18 + 2W
</span><span>18 + 2W = 30
2W = 30-18
</span><span>W= 12/2 = 6
A= L x W
A= 9 x w
</span><span>A= 9 x 6 = 45 yd square</span>
Answer:
<u><em>73.72 ft Squared</em></u>
Step-by-step explanation:
First you need to find the area of the rectangle the area of rectangle is 8x10=80. Then You take that 80=3.14x2. then you find the area by dividing it. so...
1.) 80=3.14x2
3.14x2=6.28 <u> 80=6.28 </u> (Then you divide 6.28 by 80)
80 80
Answer:
They are a and b.
Step-by-step explanation:
We have got logarithms to the base 10 here.
We know that log 10^3 = 3 log 10 ( by the law of logarithms).
Also log 10 = 1 ( by definition) so log 10^3 = 3 log 10 = 3.
