Answer:
slope = -4
Step-by-step explanation:
rise/ run = 4/1, but slope always minus, so slope = -4
Let 'x' be the distance from THE far bank where 700 is the distance to the NEAR bank
boat one has travelled 700 (rate = 700/unit time) boat two has travelled x rate = x / unit time
boat one then travels x + 400 more and boat two travels 700 + (700+x -400) more when they meet
The time is the same rate x time = distance distance/rate = time equate the distances divided by the respective rates
(700 + x + 400)/700 = ( x + 700 + (700+x-400) )/x
1100x + x^2 = 1400x + 700000
x^2-300x -700000 = 0 quadratic formula yields x = 1000
One boat travels 700 the other 1000 whe they first meet.....width of river = 700+ 1000 = 1700 m
If the value of x is 10. Then the measure of angle ∠COB will be 56°.
<h3>What is an angle?</h3>
The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
Given that A, O, and B lie on a straight line segment.
Then they make a linear angle that is 180 degrees.
Then we have
∠AOC + ∠COD + ∠DOB = 180
(3x + 94) + (x + 30) + (2x - 4) = 180
6x + 120 = 180
6x = 60
x = 10
Then the measure of angle ∠COB will be
∠COB = ∠COD + ∠DOB
∠COB = (x + 30) + (2x - 4)
∠COB = (10 + 30) + (20 - 4)
∠COB = 40 + 16
∠COB = 56°
