$-8 was the total change in value of the stock over the four-day period
Answer:
1/10
Step-by-step explanation:
This forms a right triangle with hypotenuse of length 15 and vertical component of length 4. Use the inverse of sine (vertical/hypotenuse) to get arcsin(4/15) = 15.4 degrees which rounds to 15
Final answer:
Answer choice B, 15 degrees
An exterior angle equals the sun of the two opposite inside angles:
5x = 120 + x
Subtract 1 x from both sides:
4x = 120
Divide both sides by 4:
X = 30
The answer is D. 30
