Answer:
Step-by-step explanation:
4x + 2x = 90
6x = 90
x = 15
4(15)= 60 for <LMN
2(15)= 30
Answer:
D. (25π - 50) sq m
Step-by-step explanation:
Since ABCD is a square with the area of 100, we know that the dimensions are 10 by 10. With that, we can find that triangle ABC = 50 sq m because of (h*l)/2. Since A is the center of the circle that contains arc BD, we know that 10 is the radius of the quarter-circle ABC. Using (πr^2)/4 to get the area of the quarter-circle, we get that the quarter-circle ABC = 25π sq m. But the original triangle ABC in the quarter-circle is not shaded. Therefore, we subtract 50 from 25π, which leads to (25π - 50) sq m.
I hope this helped! :D

Hi!
The sample space of this problems is the set of all the possible sales. It is divided in the disjoint sets:

We have also the set of sales of boat accesories
, the colored one in the image.
We are given the data:

From these relations you can compute the probabilities of the intersections colored in the image:

You are asked about the conditional probability:

To calculate this, you need
. In the image you can see that the set
is the union of the two disjoint pink and blue sets. Then:

Finally:

Answer:

Step-by-step explanation:
From the question we are told that
Angle 
Height of plane
