Answer:
angle four equals angle 7 because they are alternate angles in a way.
Step-by-step explanation:
First if you go diagonally up from angle 4, you get angle 5. Then you go diagonally down. That angle isn't marked so I'll call it Z. But you could do it a faster way. You see, you could replace angle 4 with angle Z and vice versa. Then angle Z is the alternate angle of angle 7. One rule you should remember:
Alternate angles are equal.
Does this help? If it doesn't make sense let me know. (When I was learning this, it didn't make sense either)

Answer:
32760
Step-by-step explanation:
There are 4 positions on the board. There are 15 possible candidates for the first position. That leaves 14 candidates for the second position. Which leaves 13 for the third position, and 12 for the fourth position.
15 × 14 × 13 × 12 = 32760
Answer:
trapezoid.
Step-by-step explanation:
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices and edges
If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram
Area of a trapezoid = 
x (sum of the lengths of the parallel sides) x height
Perimeter = sum of lengths of sides of a trapezoid
Answer: 0.317
Step-by-step explanation:
Let A be the event that the selected household is prosperous and B the event that it is educated.
Given : P(A)=0.138, P(B)=0.261
P(A and B)=0.082
We know that for any events M and N ,
Thus , 
Hence, the probability P(A or B) that the household selected is either prosperous or educated = 0.317
