Answer:
10 divided by 3 = 3.33 for each side of the triangle.
2 x 6 = 12(area of two triangles)
10(height) x 3.33(area of one side of the triangle) x 3(three rectangles) = 99.9
Add given areas:
99.9 + 12 = 111.9 rounded = 112 cm^2

Answer:
8/3 is between 2 and 3 above 2.5
11.3 is between 3 and 4 above 3.5
Step-by-step explanation:
8/3 converts to the decimal 2.666666... which means its located on the number line between 2 and 3 above 2.5.
11/3 converts to 3.6666.... which means its located on the number line between 3 and 4 above 3.5.
Draw a right triangle with horizontal base length 2, vertical length 3.
Use pythagorean thm to find length of hypotenuse:
Now use SOH CAH TOA to find correct trig ratios:
The opposite side is always the vertical side ----> 3
The adjacent side is always the horizontal side ---> 2
SOH ---> sin = opp/hyp
CAH ----> cos = adj/hyp
TOA -----> tan = opp/adj
Answer:CA, BC, BA
Step-by-step explanation:
To find the length of line cf, I first created a square and labeled the vertices a b c d. From here you know the triangle shares the vertice b. I used the lines on the square to add point e. The distance between a and e was 2, leaving us with a distance of 4 from a to b.. I used the 4 to find the missing height. knowing that the total area was 20, the height had to be 10. I extended side cb of the triangle and made a point f. The extra part measured 4 units because the side of the square was 6, so to get 10 I needed 4 more units. I have attached a picture showing this.
