B 40 m A
11. The median of the given data with the observations in ascending order is 27.5. Find the
value of x.
24, 25 , 26, x+2, x+3, 30, 33, 37
12. If a line segment AB is to be divided in the ratio 5:8 internally, we draw a ray AX such
that ∠BAX is an acute angle. What will be the minimum number of points to be
located at equal distances on ray AX?
13. State the Pythagoras Theorem.
OR
If ∆ABC ∼ ∆ DEF and ∠A= 450
, ∠C = 550
, then find ∠E.
