In the isosceles trapezoid ABCD, draw two perpendiculars AM and BL from A and B to the side CD.
Now, LM = BA = 5 m
CD = CL + LM + MD
= CL + 5 + CL (CL = MD)
= 2CL + 5
But, CD = 11
Therefore, 2CL + 5 = 11
2CL = 11 - 5
= 6
CL = 6/2 = 3m
MD = 3m
Now, consider the right triangle AMD.
We have,

= 
= 16 - 9
= 7
Hence, height of the isosceles trapezoid = AM = 
Answer: P(none of them Europeans play against each other)=
Explanation:
Since there are 8 teams in which 3 are Europeans.
So, remaining 5 teams are not Europeans
We have to take 2 teams to pair up.
And we have a condition that neither of team is European.
So the favourable outcome =
and the total outcomes=
So, by using theprobability formula i.e.
P(E)=
P(getting none of European team play against each other)=
=
=
Answer:
135
Step-by-step explanation:
all triangles have angles that add to 180. angle a is 28 angle c is 17 which makes angle BAC 135
