Answer:
sin0 = -12
Step-by-step explanation:
tan0 = sin/cos
12/5 = sin / -15/3
sin = tan0 x cos0 = 12/5 x -15/3 = -12
Answer:
45 points
Step-by-step explanation:
You could do it with proportions. Start with 18/x=40/100. then, cross multiply and you should get x=45.
Same-side interior angles where a transversal crosses parallel lines are supplementary:
The solutions to these equations can probably be done in your head:
- y = 180/(6+4) = 18
- x = (180-90)/5 = 18
The angles at the bottom of the figure, shown as different, are actually the same: 90°.
The angles at the top of the figure, shown as the same, are actually different: 108° on the left, 72° on the right.
Answer:
268.25
Step-by-step explanation:
by using the fact that one year is 365.25 days, we can subtract our 365.25 by our 97 to get 268.25, written in the equation of 365.25-97=268.25
*edit, messed up how long a year was, corrected my issue, answer & equation.
<span>Then distance traveled by Yuto to meeting point = 1,880 - D
Times taken by both to travel to meeting point are equal
Therefore, we get: 1880 - D/220 = D/250
250(1,880 – D) = 220D ------ Cross-multiplying
470,000 – 250D = 220D
- 250D – 220D = - 470,000
- 470D = - 470,000
D, or distance Lian traveled = -470000/-470, or 1000 km </span>
