M∠P = 12°
m∠Q = 90° [A tangent line to a circle is perpendicular to the radius drawn to the tangent point]
m∠O = 90 - 12 = 78°
Answer: x=78°
We can't use P = 2L + 2W because the sides have different lengths.
P = a + b + c + d
a = x
b = 2x
c = 2x - 2
d = x + 5
P = x + 2x + (2x - 2) + (x + 5)
P = <u>x + 2x + 2x</u> - 2 <u>+ x</u> + 5
P = 6x + 3
if x = 4:
P = 6 · 4 + 3
P = 24 + 3
P = 27
Step-by-step explanation:
given f(x) = 2/x and g(x) = 2/x
f(g(x)) = 2/(g(x)) = 2/2/x = x/2 × 2 = x
g(f(x)) = 2/(f(x)) = 2/2/x = x/2 × 2 = x
therefore they are inverses
since f(g(x)) = g(f(x)) = x.
