First we find the area of the two triangles on each side (keep in mind that they are equal/congruent to each other):
(24*10)/2 = 120 cm^2
Then you find the areas of the three rectangles that are left:
24*19 = 456 cm^2
26*19 = 494 cm^2
10*19 = 190 cm^2
Finally, to find the surface area of the prism:
120+120+456+494+190 = 1,380 cm^2
For the mean, add together all of the numbers together (let's call the total x) and count how many numbers there are. (let's call this number y). divide x by y, and that is your mean. for the median, put all the numbers in order, and the median is the number in the middle. if there are two numbers in the middle, add them together and divide them by 2.
Answer:
Step-by-step explanation:
<u>Trigonometric ratios</u>
where:
- is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (side opposite the right angle)
From inspection of the diagram:
- = x
- O = 8
- A = 6
- H = 10
