This is an isosceles triangle. This means that 3x is equal to (6x-21)

3x = (6x-21)
x = 7

Since x=7, you plug it into the equation it gives you. The two angles in the bottom right and bottom left are 21. All angles added together in a triangle are equivalent to 180. So 180-41=139.

y=139

You write it as 46 divide by 1058. 46 x 2 is the closest you will get to 100. 46 x 2 is 92. put it in and you have 138 left. multiply 46 x 3 and you will get 138. amswer is 23. remember to bring down the next number whwn dividing

Answer:

1/10⁶ or 0.000001

Step-by-step explanation:

For every time you have a probability of getting 1 is:

P(1) = 1/10

For all 6, the probability of outcome of 1 is:

P(1x6) = (1/10)⁶ = 0.000001
