Answer:
Step-by-step explanation:
We will use the general area formula for finding the area of triangle when you are given information for SAS, which we have been.
, where a and b are the given side lengths and C is the included angle. You can ONLY use this when you have the info for SAS in a triangle. For us,
a = 17, b = 15 and C = 35 degrees. Filling in:
Do that on your calculator in degree mode and you'll find the area to be
73.1 meters squared
Answer:
Swimming speed in still water is approximately 1.5 mph
Step-by-step explanation:
Given the speed of the current = 1 mph
distance she swims upstream =2 miles,
the total time = 5 hours.
She swam 2 miles upstream against the current and 2 miles back to the dock with the current. The formula that relates distance, time, and rate is
Let x be the speed in still water.
Then her speed with the current is x + 1, and
her speed against the current is x – 1.
Total time is equal to 2 miles with upstream and 2 miles downstream.
Now Using quadratic formula to solve above equation we get;
Since speed must be positive, Hence speed of still water is about 1.5 miles per hour.
