Answer:
9 miles
Step-by-step explanation:
3 times 3 is 9
<h3>===> Exercise 1</h3>
Add 8 to both sides.
Add 7 and 8 to get 15.
Divide both sides by 3.
Divide 15 by 3 to get 5.
<h3>===> Exercise 2</h3>
Subtract 9 from both sides.
Subtract 9 from −15 to get −24.
Divide both sides by 8.
Divide −24 entre 8 para obtener −3.
<h3>===> Exercise 3</h3>
Swap the sides so that all the terms of the variables are on the left side.
Add 13 to both sides.
Add 8 and 13 to get 21.
Divide both sides by 3.
Divide 21 by 3 to get 7.
<h3>===> Exercise 4</h3>
Subtract 22 from both sides.
Subtract 22 from 4 to get −18.
Divide both sides by 6.
Divide −18 entre 6 para obtener −3.
<h3>
===> Excercise 5</h3>
Swap the sides so that all the terms of the variables are on the left side.
Subtract 51 from both sides.
Subtract 51 from 84 to get 33.
Divide both sides by 11.
Divide 33 by 11 to get 3.
<span>For 50°, answer is 65°
For 90°, answer is 45°
For 150°, answer is 15°
A linear pair of angles adds up to 180° by definition. So the new angle drawn by the ray will have an angle of 180°-a where a is the measure of the original angle. And the bisector of that new angle will be (180°-a)/2. So with that in mind, let's calculate the new measures of the described construction.
50°: (18° - 50°)/2 = 130°/2 = 65°
90°: (180° - 90°)/2 = 90°/2 = 45°
150°: (180° - 150°)/2 = 30°/2 =15°</span>
