Answer:
Option(1)
Step-by-step explanation:
By applying secant rule in the given right triangle,
secθ = 
From the picture attached,
Opposite side of angle θ = 5 units
By applying Pythagoras theorem,
(Hypotenuse)² = (leg 1)² + (leg 2)²
= (10)² + 5²
= 125
Hypotenuse = √125
= 5√5
Now substitute these values in the expression of secθ,
secθ = 
secθ = √5
Option (1) is the correct option.
Answer: The least common denominator is 12
x= -3/12
Simplified: -1/4
Step-by-step explanation:
Do 7/12 - 5/6
7/12 - 10/12
= -3/12
Simplified: -1/4
Answer:

Step-by-step explanation:
We know

in the third quadrant 
We use a scientific calculator to find the inverse cosine of -0.9041 to find

Since this angle is not in the required quadrant we must find the other angle who has the same cosine. The required angle is equidistant from the found value from the 180 degrees angle, so our solution is

Answer:
yay thx
Step-by-step explanation:
Earthquakes with a magnitude of 3 are usually not felt or are only felt by a few people at rest (mostly on higher floors of buildings).
