Answer:
d =
Step-by-step explanation:
The distance formula is d =
Plug in the points.
d =
Solve
d =
Simplify by separating 18 into 9x2
d =
Take the square root of 9 to finish simplifying
d =
X + x + x+ 21 = 180
3x = 180 - 21
3x = 159
x = 159/3
x = 53° ← the measure of <span>each of the smallest angles
53 + 21 = 74</span>° ← the measure of the largest angle
Answer:
-210 degrees.
Step-by-step explanation:
That is 150 - 360
= -210 degrees.
Answer: False
Step-by-step explanation:
No, the number of sitcker in each row and coumn is 3;
6 faces------------------54 colored stickers
1 face-------------------- x
x=(1 face * 54 colored stickers) / 6 faces=9 colored stickers.
1 face is a square,therefore the number of rows is equal the number of columns.
number of stickers=number of rows * number of columns
number of rows=x
number of columns=x
9=x²
x=+√9=3
Answer: the number of stickers in each row and column is 9.
