Answer: 
Step-by-step explanation:
Given
Here the given figure can be divided into two shapes i.e. rectangle and a trapezium
For rectangle ABCD Area = 
Area of trapezium CEFD Area is ![\frac{1}{2}[\text{sum of non-parallel sides}]\times[\text{distance between them}]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5B%5Ctext%7Bsum%20of%20non-parallel%20sides%7D%5D%5Ctimes%5B%5Ctext%7Bdistance%20between%20them%7D%5D)
![\Rightarrow \frac{1}{2}\times [10+17][10]=135\ cm^2](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%5B10%2B17%5D%5B10%5D%3D135%5C%20cm%5E2)
Total shaded area 
Answer:
Here, we have:
P(5 days snow in this 8 days) = 8C5 x (0.85)^5 x (1 - 0.85)^3 = 0.084
P(6 days snow in this 8 days) = 8C6 x (0.85)^6 x (1 - 0.85)^2 = 0.238
P(7 days snow in this 8 days) = 8C7 x (0.85)^7 x (1 - 0.85)^1 = 0.385
P(8 days snow in this 8 days) = 8C8 x (0.85)^8 x (1 - 0.85)^0 = 0.272
Add up those above, then the probability that it will snow AT LEAST five of those days in February:
P = 0.084+ 0.238 + 0. 385 + 0.272 = 0.979
Hope this helps!

Answer:
i only know cos
cos0 = 8/9
Step-by-step explanation:
Answer:
x = 23
Step-by-step explanation:
The exterior angle = sum of the 2 opposite interior angles, hence
2x + 3 + 51 = 100
2x + 54 = 100 ( subtract 54 from both sides )
2x = 46 ( divide both sides by 2 )
x = 23
