The 3 inside angles of a triangle need to equal 180
you have 80 +60 = 140
so 51+x has to equal 180-140 or 40 degrees
51+x = 40
subtract 51 from each side
x = 40 - 51
x = -11
Answer:
18000
Step-by-step explanation:
12 is a dozen,
1500 x 12 = 18000
3 to the -2 power is basically 3x-3, which is -9, and -5 to the -3 power is (-5)(-5)(-5) which is equal to -125. hope that helped you out, bud!
Answer:
Its probably 240
Step-by-step explanation:
If you divide 360 into 12 parts, you get 30 for each part, 8x30=240, so the answer is 240º I think, dont take my word for it though
Answer:
2 <= x < 8
Step-by-step explanation:
2 is less than or equal to x and the symbol for that is <=
the least number should also be on the left side
8 is greater than x so the symbol is <
8 is the biggest number and goes on the right
