Answer:
Angles of the isosceles triangle are 36°, 72° , 72°
Step-by-step explanation:
Vertex angle : Base angle = 1 : 2
Vertex angle = x
Base angle = 2x
Sum of all angles of a triangle = 180°
x + 2x + 2x = 180°
5x = 180
x = 180 ÷ 5
x = 36°
2x = 2 *36 = 72°
Angles of the isosceles triangle are 36°, 72° , 72°
The appropriate domain and the range are x > 0 and y > 0, respectively and the speed is 2.5 miles per hour in order to travel 20 miles in 8 hours.
<h3>How to determine the reasonable domain?</h3>
The function is given as:
xy = 20
The value of x and y cannot be negative and they cannot be 0.
This means that the domain and the range are x > 0 and y > 0, respectively
<h3>The graph of the function</h3>
See attachment for the graph of xy = 20
<h3>The estimate of the speed</h3>
We have:
Distance = 20 miles
Time = 8 hours
The speed is calculated as;
Speed = Distance/Time
This gives
Speed = 20/8
Evaluate
Speed = 2.5 miles per hour
Hence, the speed is 2.5 miles per hour in order to travel 20 miles in 8 hours.
