I got 441 times using this formula 7x3^2=x
Well, the first one is 2/40=1/20. The 2nd one is 1/39. You multiply these to get 1/780.
Left page numbers are always even and right page will have a number 1 greater that the left. so its not possible to have a sum of 87.
If even page is 2n then right page = 2n + 1:-
2n + 2n + 1 = 87
4n = 86
n = 86 / 4 = 21.5 and 2n = 43 but left page is even so its not possible to have a sum of left + right = 87.
Answer:
y-4=1(x-6) and y= x 10
Step-by-step explanation:
Answer: x= 98°
Step-by-step explanation:
Concept:
Here, we need to know the concept of the "Exterior Angle theorem"
The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two opposite angles of the triangle.
If you are still confused, you may refer to the attachment below for a graphical explanation.
Solve:
x = 53 + 45 = 98°
Hope this helps!! :)
