Answer:
In a right triangle, as the angle increases, the value of the sine increases.
Step-by-step explanation:
Think of the unit circle, a circle with radius 1 unit centered at the origin which is the point with coordinates (0, 0). Draw a radius of the circle from the center, to point (1, 0) on the positive x-axis. The angle formed by this radius and the positive x-axis is 0 degrees. This is an angle in standard position. The endpoint of the radius on the circle has a y-coordinate. The y-coordinate is the sine of the angle. As you choose points on the circle going up from the positive x-axis, the angle formed by the radius connected to the point on the circle and the positive x-axis increases in measure until it coincides with the positive y-axis, where it has a measure of 90 degrees. The sine of the angle is always the y-coordinate of the point on the circle. As the angle increases from 0 to 90 degrees, the y-coordinate increases from 0 to 1. The acute angles of a right triangle can have measures of only between 0 and 90 degrees.
Answer: In a right triangle, as the angle increases, the value of the sine increases.
Answer:
a) s1 is 4 km/h because it is given. t1 is 30 min. s2 is 8 km/h. d is 4 km because given
b) d2 is 2 km because he travels 30 min at 4 km/h which is 2 km
c) d2 is 2 km because he travels 30 min at 4 km/h which is 2 km and 4 km-2 km is 2 km
d) 2 km at 8 km/hour is 1/4 hour which is 15 minutes so t2 is 15 min.
e) 3:45+15 min is 4:00
