Multiply the length times the width. :)
Answer: 47°
To find the answer, you must use sin⁻¹ (INVERSE SIN) to find x which is the reference angle.
If you look at the triangle, you can tell that we must use sin because we have an opposite (39) and an hypotenuse length (53).
Sine = OPPOSITE/Hypotenuse
So you use a calculator and insert sin⁻¹ 39/ 53.
Or depending on your calculator you could insert 39/ 53, then sin after it.
The calculator would give you <u>47.379009047.</u>
But you have to round 47.379009047 to the nearest degree, so your answer is 47°.
<h2>At time 9 : 00 AM they are 135 miles apart.</h2>
Step-by-step explanation:
Nancy leaves the house at 7:00 A.M. and averages 15 miles per hour. Mark leaves at 7:15 A.M. and averages 60 miles per hour.
Let the time after the start of Mark when they are 135 miles apart be t hours.
Time traveled by Nancy = t + 7:15 - 7:00 = t + 15 minutes = (t+0.25) hours
They are traveling in the opposite direction so,
Distance between them = Speed of Nancy x Time of travel of Nancy + Speed of Nancy x Time of travel of Nancy
135 = 15 x (t+0.25) + 60 x t
135 = 15t + 3.75 + 60t
75t = 131.25
t = 1.75 hours = 1 hour 45 minutes
Time = 7: 15 + 1 hour 45 minutes = 9 : 00 AM
At time 9 : 00 AM they are 135 miles apart.
