- What is supplementary angle ?
- When sum of two angles is 180°, then each of those two angles will be considered to be the supplementary angle of each other.Example : 150° and 30° are two angles, and their sum is 180°. So, 150° and 30° are supplementary angles.
____________________
<u>Explanation</u> :-
It's given an angle measures 168° more than the measure of its supplementary angle. We are asked to find measure of each angle!
- Let, one of the supplementary angle be "x" . Then the other angle becomes " (x + 168)° "
Sum of these two angles is equal to 180° . Since they are supplementary angles.
Then –
- The measures of the two given angles are 6° and 174°.

The car is traveling at 95 km/h, and the train is at 75 km/h.
Remember the train is 1 km long.
a)
With respect to the train the car is not moving as much as 75 km/h.
The car with respect to the train is moving as much as 95 - 75 = 20 km/h
Recall the train is 1 km long.
Time to cover the 1km long train = Distance / speed = 1 / 20 = (1/20) hour.
= (1/20)*60 minutes = 3 minutes.
So the car would pass the train in 3 minutes.
b)
Now if they are traveling in opposite directions;
the car with respect to the train = 75 + 95 = 170 km/h
Time to cover the 1km long train = Distance / speed = 1 / 170 = (1/170) hour.
<span>= (1/170)*60 minutes = (6/17) minutes
</span>
= (6/17)*60 seconds = 360/17 seconds ≈ 21.176 seconds.
Answer:
x183'324
Step-by-step explanation:
The correct answer was 8 / 17
Because
AB^2 + 60^2 = 68^2
AB^2 = 4624 - 3600 = 1024
AB = 32
Sin S = Opp/Hyp = 32/68 = 8 / 17
