A. 20. plug 20 in to both equations and they will be equal to eachother
Answer: 430 cm²
Step-by-step explanation:
1) Front x Back= 15 x 7 x 2= 210 (We do time 2 because there are two of the same shapes ex. there are two squares that are both 16 ft so just do 16 x 2)
2) Right x Left= 7 x 5 x 2 = 70
3) Top x Bottom= 15 x 5 x2 = 150
4) Add. 150 + 210 + 70 = 430 cm²
Hope that helped! :)
Answer:
it may be C but I'm not sure
Well i think you have to draw a picture .so Let x be the vertical distance of the ladder from the top of the wall to the ground. Start with a 65degrees angle. sin65degrees = x/11,x = 9.969.If the angle is less than 65degrees, then x will be less than 9.969. The answer is it is not possible
