Answer:
cm²
Step-by-step explanation:
Surface area of the composite figure = Surface area of the lateral surfaces of the given pyramids
Lateral surface area of a square pyramid = 4
Therefore, lateral surface area of the pyramid
= ![4[\frac{1}{2}(24)(5)]](https://tex.z-dn.net/?f=4%5B%5Cfrac%7B1%7D%7B2%7D%2824%29%285%29%5D)
Now lateral surface area of the composite figure = 2(lateral surface area of two pyramids)
= ![8[\frac{1}{2}(24)(5)]](https://tex.z-dn.net/?f=8%5B%5Cfrac%7B1%7D%7B2%7D%2824%29%285%29%5D)
Therefore, Expression for the surface area of the given composite figure is,
cm²
You're gonna have to mention how much it costs to travel each mile, the price of gas, etc., to get a real answer.
Only the third one make sense I believe
Answer:
c = 43
Step-by-step explanation:
sin theta = opposite side / hypotenuse
sin 28 = 20/c
Multiply each side by c
c sin 28 = 20/c *c
c sin 28 = 20
Divide each side by sin 28
c sin 28 /sin 28 = 20/sin 28
c = 42.60108936
To the nearest whole number
c = 43
