The answer is B
Have a good day!
Answer:
In the case of the equilateral triangle, , the exterior angle, plus 60 equals 180. Subtracting 60 from both sides of this equation gives us a value of equal to 120. This means that the exterior angle of an equilateral triangle is equal to 120 degrees. The sum of all the exterior angles is always 360 degrees.
Step-by-step explanation:
15 the answer is 15 because 15 x 5 = 75
Answer:
32 degrees fahrenheit
Step-by-step explanation:
Since the measure of angle is
The measure of its reference angle =
=
Now we have to compute the value of
The value of () lies in the fourth quadrant. In fourth quadrant, the value of tan is always negative.
So,
= -1.
