Answer:
Step-by-step explanation:
By geometric mean property:
By Pythagoras Theorem:
Answer:
see below
Step-by-step explanation:
6 cot ^2 (y) ( sec^2 (y) -1) = 6
We know that ( sec^2 (y) -1) = tan ^2(y)
6 cot ^2 (y) tan ^2 (y) = 6
We know cot = cos/ sin and tan = sin / cos
6 cos/ sin ^2 (y) sin/cos ^2 (y) = 6
6 ( 1) = 6
6=6
A = 9*14 + 12*8
A = 126 + 96
A = 222 m²
You just have to add the areas of the two rectangles.
Hope this helps !

What we’re the two temperatures in both locations? Ima need some info to answer lol
When we make a solution, the solute doesn't go away. All the solute we use stays in the solution it only dissolve in the solution.
The total mass of solution is always equal to the mass of solvent added to the mass of solute.
Therefore 5gram + 20 gram = 25 gram of solution.
5/25×100= 20%
