The answer would be D)90 degrees
Answer:
1) b would be easier because it’s 1/2bh and since the base of 10 is easily divisible by 2 you don’t have to deal with fractions.
D=sqrt (x2-x1)^2+(y2-y1)^2
D=10
Step-by-step explanation:
There are 10 digits 0 1 2 3 4 5 6 7 8 9 if we can't use 0 and 1 then there are only 8 choices for the first digit and only 2 choices for the second digit and 10 for the third so there are 8*2*10 =160 possibilities. I think ???
