Answer:

5

Step-by-step explanation:

by pythagoras theorem

(hyp)^2=(leg1)^2+(leg2)^2

the hypotenuse is the side opposite to 90 degree (BC=13)

AC=leg 1 = 12

13^2=12^2 + leg 2^2

169=144+ leg 2^2

leg2 ^2=169-144

leg2^2= 25

leg2= root 25

leg2=5

Answer:

5

Step-by-step explanation:

The first thing to think about when doing a problem is to look in the angles. BAC is a right angle, but that does not help. The next thing to notice is BA looks roughly about 1/2 the size of AC. That answer makes the most sense so the answer is 5.

trapecia [35]

Answer:

As the average has increased the height of the new player must be more then the height of the player which was injured.

The difference between the previous average and the new average is 0.01 m.

Therefore the average is increased by 0.01 m.

Therefore the total height of all the players is increased by 0.01*11=0.11 m

Therefore as the increase in the total height is made by the player with height 1.85 m,the height of the player who was injured is 1.85–0.11=1.74 m

The height of the player who was injured is 1.74 m
