Answer:
3/5
Step-by-step explanation:
I'm not completely sure but from what I see it says 'sin <em>C </em>' and both 12 , 20 are on C.
so i simply just did 12/20
reduced once - 6/10
reduced twice - 3/5
Answer:
20 x 20 feet
Step-by-step explanation:
First I just drew out two squares, one was the first un-cut square and the second is the cut one. Since we know that the area of the smaller square is 144, and Area is just side^2 , we know that all the sides of the smaller square are 12. Now, all we have to do is add 8 to 12 to get the original lawn. The original lawn was a 20 x 20 ft lawn.
Answer:
50 miles
Step-by-step explanation:
20 multiplied by 2.5 = 50
Answer:
128
Step-by-step explanation:
You get this by doing PEMDAS. We start with parenthises and then exponet so we do 4x4 which is 16 now we have 18-16+2 so we go in order and the anwser for the first line is 4 but we have an exponet so 16
now the second line we divide 1 and 4 we get 4 and now we multiply by 1/2 and we get 2. now we have 16/2 that is our anwser and we can put that to a whole number of 128
115 degrees because there are 180 degrees in a triangle so let the missing angle in the trinagle be x. Then we have x+75+40=180. Solving for x and subtracting that from 180 (supplementary angles) we get 115 degrees.
