Those arcs are congruent since the chords inside are congruent. so we can just make the equation
2x= x+40
which simplifies down to x=40
Answer:
Events A and B are independent if and only if P(A and B) = P(A)P(B). If you know these probabilities, you can check to see if this holds.

Answer:
I won't give you the answer straight away so you take the time to read my answer and understand
Step-by-step explanation:
We knoe that 2 to the third is 8. when you square to a negative power, you do squaring normally, and then take the reciprocal of that number. so 8 to the second power is 64, and we flip it over, sp the answer is 1/64
Answer:
1/3776965920
Step-by-step explanation:
1/42 x 1/41 x 1/40 x 1/39 x 1/38 x 1/37 = 1/3776965920
The formula for finding the area of a triangle is 1/2 base * height = area. In this case, we know the area and the base. Let's say the variable h represents height. We fill in the area and base with our known values to get 1/2 (30) * h = 450. Then, we solve. Half of 30 is 15, so 15h is equivalent to 450. Then, divide both sides by 15 to get h is equivalent to 30. To double check, fill in the base and area, and the newly found height. If the values make the equation make sense, the height is right. 1/2 (30) * 30 = 450. 15 * 30 is 450, so the height is 30 inches.
