In this attached picture, we can prove that triangles AOB and COD are congruent. ∠CDO and ∠ABO are equal because they are alternate angles. Similarly, ∠OAB and ∠OCD are equal because they are alternate angles, as well. We have a rectangle and in the rectangle, opposite sides are equal; AB = CD. Then, because of Angle-SIde-Angle principle, we can say that triangles AOB and COD are equal. If triangles are congruent, then OD = OB and OC = AO. Applying congruency to the triangles ACD and BCD, we can see that these triangles are also congruent. It means that the diagonals are equal. Since, OD = OB and OC = AO, it proves that the point O simultaneously is the midpoint and intersection point for the diagonals.
Answer:12
Step-by-step explanation:
Square root of 16x9=12
9514 1404 393
Answer:
Step-by-step explanation:
The letters designating the end points of the segment may be listed in either order. The symbol over the pair of letters is a bar with no arrows on it.
__
Arrows on the bar over the point names indicate a ray (arrow to the right) or a line (double-ended arrow). This is only a segment, which does not extend beyond its end points.
Answer: The number of days would be 7 days.
Step-by-step explanation:
Since we have given that
Variance = 30°
Standard deviation = √30 = 5.47
Mean = 4°
At 95% confidence, z = 1.96
So, number of days that the researcher select to measure the temperature would be
Hence, the number of days would be 7 days.
5 is the answer. Any number that ends in 5 or 0 allows 5 to go into it.
