Answer:
The speed of the biker is 15
Step-by-step explanation:
First, you call the speed of the walker x, and the speed of the biker 2.5x.
Then you know that speed times time equals distance, so you set up and equation. You do x times 2, which is 2x, and then 2.5x times 2, which is 5x. Then, since the distance between them is 18 miles, the equation would be 5x-2x=18. You would get 3x=18, and x is 6. So 6 is the speed of the walker, and 6 times 2.5 = 15, so the speed of the biker is 15.
If a 4 sided figure has 360°...for each side we add, we add 180°.
you have a 7 sided figure (360° + 3(180°) = 900°)
adding up your angles (781) and subtract it from 900 =
x = 119°
Using the interactive protractor, the measure of the angle JHG is 115°
<h3>How to determine the measure of the angle?</h3>
The image that completes the question is added as an attachment.
The question requests that we determine the measure of JHG using a protractor.
To do this, we set one end of the protractor at 0°.
Then, we take the measurement of the other end
Using the interactive protractor, the other end stops at 115°
Hence, the measure of the angle JHG is 115°

400 - 3x = 163
Add 3x to both sides.
400 = 163 + 3x
Subtract 163 to both sides.
237 = 3x
237/3 = 79
