The worksheet pic is not clear
8 and 10 are possible lengths of the third side.
Answer:
Step-by-step explanation:

we take the LHS so here goes,

since ,
the identity becomes,

now, we know,
and 
the identity becomes,


sin A and cos A cancel out it becomes zero

Splitting the denominator the identity becomes

Hence,

L-1.5l < 0 is not true
absolute value is the distance away from zero
-1.5 is 1.5 away from zero, so l-1.5l=1.5
1.5 is greater than zero, therefore, l-1.5l<0 is not true
Answer:
1/4=0.25=25%
Step-by-step explanation:
A coin has two sides, heads and tails, and if you take 100% divided by two you get 50, you want to know what is the probability it will land on tails TWICE so divide 50 by two and you get 25.
1/2=50
1/4=25
0.25 x 100= 25%
hope that helps
