Answer:
Step-by-step explanation:
We are given a ΔPQR in which S is the mid point of QP , T is the mid point of QR
, U is the mid point of PR
i) is true
⇒
Using mid segment theorem which states that In a triangle, the line joining the midpoints of any two sides will be parallel to the third side and that same line joining the midpoints is also half of length of third side .
So, by refering image we can see that UT is the line joining the two mid points . So, by using above theorem 1/2QP=UT and UT is parallel to PQ
Thus, (i) statement is true
⇒
Answer:
Step-by-step explanation:
3. sin^2A + cos^2A = 1 (formula )
1 + tan^2 theta = sec^2 theta (derived from the formula sec^2 theta - tan^2 theta )
b.2x = 12 (by comparing the corresponding element)
x = 12/2
x = 6
3y = 12 (by comparing the corresponding element)
y = 12/3
y = 4
mean = sum of data / no of data
4+7+5+9+11+6 / 6
42 / 6
7
mean = 7
to find median arrange the data from ascending to descending order (from smallest to biggest)
data = 3,4,6,8,10,12
median = (N +1)/2 (N means no of data )
=6 + 1/2
=7/2
=3.5
=3 th term + 4 th term /2
=6 +8 / 2
=14/2
=7 median = 7
to find value of theta
90° + 50° + theta = 180° (sum of interior angles of a triangle)
140° + theta = 180°
theta = 180° - 140°
theta = 40°
therefore theta = 40°

Answer:
234 miles a day
Step-by-step explanation:
<em><u>The whole trip was for 2 weeks (7*2=14 days).</u></em>
<em><u>Since 1 day from each week they took rest, they drove for (14-2(1)=12 days) 12 days.</u></em>
So a total of 2808 for 12 days. The average is 2808 divided by 12 days:

The answer is 234 miles a day
Solve for y, add 8x to the other side then when y is isolated divide both sides of the question by two and that should give you your final equation and you should have the slope and yint
