Answer:
f(x) = cos(x)
Step-by-step explanation:
tanx cscx = (sinx/cosx) * (1/sinx) = 1/cosx
1/f(x) = 1/cosx
f(x) = cos(x)
The answer would be n+n+2/2n+2 as Jide is n and his twin sister is two years older so she would be his age (n) plus 2 so n+n+2=2n+2

Answer:
∠MDP = 90° = Right angle
∠MDP = 180° = Straight angle
∠ODM = 90° = Right angle
∠OND = Not an angle
∠NDO = 90° = Right angle
∠NDM = 180° = Straight angle
∠PMN = Not an angle
∠PDO = 180° = Straight angle
∠PDN = 90° = Right angle

We know that
[area of a circle ]=pi*r²
diameter=4 in
r=4 in/2-----> 2 in
so
area=pi*2²-----> area of the circle=4*pi in²
the answer is
the area, in square inches, of the circle is <span>3.14 • 2²</span>
