Answer:
b 0.25
Step-by-step explanation:
20 ÷ 5 = 4 so 1/4 of 20 or 0.25 is 5
Answer:
sin θ = 
Step-by-step explanation:
Given that,
cos θ = 
From the trigonometric functions,
cos θ = 
⇒ adjacent =
, and the hypotenuse = 3
Let the opposite side be represented by x, applying the Pythagoras theorem we have;
=
+ 
=
+ 
9 = 3 + 
= 9 - 3
= 6
x = 
Thus, opposite side = 
So that,
sin θ = 
= 
Therefore,
sin θ = 
If the diagonals of a parallelogram are congruent, then it's a rectangle .
