Let us first find the angle adjacent to θ. To find this we can construct a right triangle by drawing a line segment from the point (-12,5) straight down to the x-axis. Using right triangle trig...

tan(adjacent angle)=5/12

adjacent angle=22.62 degrees

Since the two angles make a linear pair.

θ=180-22.62=157.38 degrees

cos(157.38 degrees) = -0.92

answer: -0.92

Phoenix [80]

Answer:

The answer is B) 1/25

Step-by-step explanation:

This is because given that f(x) = 5^x

Hence, f(-2) would be 5^-2, which is equal to (1/5^2) => 1/25

Because a^-b can be written as 1/a^b
