Answer:
√3 - 2.
Step-by-step explanation:
Let A = 330 degrees so A/2 = 165 degrees.
tan A/2 = (1 - cos A) / sin A
tan 165 = (1 - cos 330) / sin 330
= (1 - √3/2) / (-1/2)
= -2(1 - √3/2)
= -2 + 2 * √3/2
= √3 - 2.

Answer:
80
Step-by-step explanation:
The two sides of the triangle are the same so the bottom right angle is also 50. 50 + 50 is 100 and 180 - 100 is 80 so x=80. I subtracted 100 from 180 because all the angles in a triangle add up to 180.
Answer:
I think The answer is A
Step-by-step explanation:
Well 1.25 meters per second so 1.25 x 8 = 10
