Answer: 12
Step-by-step explanation:
this is a right angled triangle so you use the pythagorean theory
which is a^2 + b^2 = c^2
you have c and b already. c is the hypotenuse.
a^2 + 16^2 = 20^2
a^2 + 256 = 400
a^2 = 400 - 256
a^2 = 144
then you square root 144 and get..
a = 12
Answer:
Step-by-step explanation:
The angle of 2 is 75 degrees.
Angle 1 = 180 - 75 = 105 degrees
The answer is x bc when you decreasing the interval f(x) it will equal (-2)
