If i'm not mistaking, the value of the missing angle should be 65 degrees and i got this by subtracting 70 and 45 from 180 (180 is the total value of angles in a triangle) and i got 45 by dividing the right angle into 2. So we have 180-45-70= 65.
I hope it helps
There's 180 degrees in a triangle so and the two angles and then subtract by 180
79.(b)this is because you have six choices, 3 red, 1 blue, 1 yellow, and 1 green and since it says not red you only have 3 choices, blue yellow and green, so the fraction would be 3/6. You can simplify the fraction by dividing it by 2 and you would get 1/2.
80.the answer will still be (b) which is the same explanation for 79.
81. (C) because remember that the first time you only had a 50% (1/2) chance of getting red and the second chance of getting a red will be the same but not
Its not likely You can get a red.
8.5 miles/minute. You divide
There are 6 sides to a hexagon and each side of the fence will be 6+2 = 8 feet
So you'll need 8*6 = 48 feet of fencing.
