Answer:
It's 975 because they traveled for 17 hours and had stopped for 2 hours do 17-2=15, so 15×65=975
Step-by-step explanation:
Option C:
x = 90°
Solution:
Given equation:

<u>To find the degree:</u>

Subtract 1 + cos²x from both sides.

Using the trigonometric identity:




Let sin x = u

Factor the quadratic equation.

u + 2 = 0, u – 1 = 0
u = –2, u = 1
That is sin x = –2, sin x = 1
sin x can't be smaller than –1 for real solutions. So ignore sin x = –2.
sin x = 1
The value of sin is 1 for 90°.
x = 90°.
Option C is the correct answer.

Step-by-step explanation:
Divide 6 by 4 then multiply by 24.
Rate tables are useful because it has something that stands for something else. For example,
