Question
In a right triangle PQR, the angle Q measures 90.The. the angles P and Q are
- supplementary
- complementary
- obtuse
- Right
Hint:
using the property of sum of angles in the triangle is 180.Find the relation between angles P and Q.
The correct answer is: complementary
ANS :- Option B
Explanation :-
In triangle PQR, angle Q measure 90º.
∠P +∠Q +∠R = 180º (sum of angles in a triangle)
∠P + 90º +∠R = 180º
∠P +∠R = 180º - 90º = 90º
If sum of two angles is 90 Then those angles are called complementary angles.

The line graph above shows the average price of one metric ton of oranges, in dollars, for each of seven months in 2014.
Between which two consecutive months shown did the average price of one metric ton of oranges decrease the most?
Note:
A simpler way of solving this question is to check where the decrease in the graph has the steepest slope between two months. It is clearly between the months June and July. Here, it is obvious; but that may not be the case in other problems. So, we need to always calculate the actual decrease in the value.

The scatterplot above shows the total number of home runs hit in major league baseball, in ten-year intervals, for selected years. The line of best fit for the data is also shown. Which of the following is closest to the difference between the actual number of home runs and the number predicted by the line of best fit in 2003?
Note:
A line of best fit is also called a trendline. The equation of a line of best fit can be represented as y = m x + b , where m is the slope and b is the y-intercept. This is the equation of a line. It is a line that minimizes the distance of the actual homeruns from the predicted homeruns.
