Answer:
1/2
Step-by-step explanation:
(3/8)+(1/8)
(3+1)/(8)
(4/8)
(1/2)
Answer:

Step-by-step explanation:
The cotangent of theta is:

For pi/2 < theta< pi
This means that the angle is in the second quadrant. In the second quadrant, the cosine is negative and the sine is positive. This means that the cotangent will be negative.
Secant:

In this question

So

Using cross multiplication



Now we apply the following trigonometric identity:






Since the angle is in the second quadrant, the sine is positive.

Finally, the cotangent:



Hey there!
We know that ,
Circumference is a circle = 2 pi r
=> 2 pi r = 50.24
=> r = 50.24/2 x 3.14
=> r = 78.8 m
But to find diameter , d = 2 x radius => 2 x 78.8 = 157.73 which is approximately 158
Option d is correct
Answer:
B. There is nothing wrong with the statement
Answer:
Step-by-step explanation:
sum of exterior angles=360°
each exterior angle=360/20=18°
each interior angle=180-18=162°
