Answer:
8 = x
Step-by-step explanation:
all three sides are equal, so it is an equilateral triangle
if it is an equilateral triangle, each angle is 180/3 = 60 degrees
therefore
60 = 7x+4
subtract 4 from each side
60-4 = 7x+4-4
56 = 7x
divide by 7 on each side
56/7 = 7x/7
8 = x
Slope: (y2-y1)/(x2-x1)
(8-2)/(1+1) = 6/2 = 3
The slope is 3
Answer:
125
Step-by-step explanation:
For arithmetic sequence: aₙ = a₁ + (n-1)d Sₙ = n/2 * (a₁ + aₙ)
a1+a4+a7+a10 = a₁ + (a₁ + 3d) + (a₁ + 6d) + (a₁ + 9d) = 4a₁ + 18d = 2 * (2a₁ + 9d)
2 * (2a₁ + 9d) = 50
2a₁ + 9d = 25
a1+a2+a3...+a10 = 10/2 * (a₁ + a₁₀) = 5 * (a₁ + a₁ + 9d) = 5 * (2a₁ + 9d)
a1+a2+a3...+a10 = 5 * 25 = 125
Answer:
108°
Step-by-step explanation:
You convert the percentages into degrees by taking the percentage of the candy then you divide it by the total percentage of the pie chart of which is 30% divided by 100% then you multiply it by 360 then you'll get your answer to be 108°
