a straight line = 180 degrees
so the missing angle is 180 - 130 = 50 degrees
Answer:
See explanation
Step-by-step explanation:
(4)
Using the sine ratio in the right triangle
sinΘ =
=
, thus
Θ =
(
) ≈ 51.1°
(5)
Using the tangent ratio in the right triangle
tanΘ =
=
, thus
Θ =
(
) ≈ 38.7°
Answer:
It takes 4.75 hours to travel 247 miles.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
A car travels at an average speed of 52 miles per hour.
This means that in 1 hour, the car travels 52 miles. How many hours for it to travel 247 miles?
1 h - 52 m
x h - 247 m
Applying cross multiplication



It takes 4.75 hours to travel 247 miles.
Convert liters to milliliters so that you have one unit for all of the amounts in the question.
1 liter is equal to 1000 milliliters, so multiply the 1.5 liters you have by 1000:

Since you drank 295 milliliters, and your friend drank 135 milliliters, you will subtract those values from the amount in the bottle:

There is
1070 milliliters of water left in the bottle. If you want to find the amount remaining in the bottle in liters, divide the amount remaining by 1000 to convert milliliters to liters:

Converted back into liters, there is
1.07 liters of water left in the bottle.
