The equivalent of sec (-270) will be found as follows:
we add our angle to 360°
-270+360
=90
But sec(-270) is a positive value, this implies that the angle that will give us the same answer as sec (-270) should also give us the positive value. This means that 90 is our answer since it will give us the positive sec value.
The answer is d. sec(90)
Answer:
Step-by-step explanation:
Angles 1 and 5 are in corresponding positions, so since A and B are parallel to each other, angles 1 and 5 are also congruent. If they are congruent, then that have the exact same measure. That means that if the sum of them is 100, each one has a measure of 50 degrees.
Angle 4 is vertical to angle 1, so that means that angles 1 and 4 are congruent. If angle 1 measures 50, then so does angle 4.
Answer:
x = (8√3)/3
Step-by-step explanation:
Reference angle = 30°
Hypotenuse = x
Side length adjacent to reference angle = 4
Apply CAH, thus:
Cos 30 = Adj/Hyp
Cos 30 = 4/x
x × Cos 30 = 4
x = 4/Cos 30
x = 4/(√3/2) (cos 30 = √3/2)
x = 4 × 2/√3
x = 8/√3
Rationalize
x = (8 × √3)/(√3 × √3)
x = (8√3)/3
