In one sentence, describe what the following article is about: In order to turn on Remote Desktop, you must be on an account that has administrator privileges, and the account must have a password enabled. Click the multicolored Windows logo in the bottom-left corner of the screen. The Start menu will pop up. It's on the right side of the Start menu. Doing so opens the Control Panel window. Click the "View by:" drop-down box in the upper-right side of the Control Panel window, then click Large icons in the resulting drop-down menu. If you already see "Large icons" next to the "View by:" heading, skip this step. It's a heading near the bottom of the window. You may have to scroll down to see this option. This link is in the upper-left corner of the window. Doing so opens a new window. It's at the top of the new window. If you don't see this option, first make sure you're on the right tab by clicking Remote at the top of the window. Skip this step if the box is already checked. It's in the middle of the pop-up window. Doing so allows you to connect to this computer from any computer that runs Remote Desktop (e.g., a Windows 10 computer) in the future. Skip this step if this box is already checked. If you want to allow Remote Desktop access to another user account on the target computer, do the following: Click Select Users. Click Add. Click Advanced. Click Find Now. Scroll down in the pane at the bottom of the window and double-click the name of the user you want to add. Click OK on the top two open windows. It's at the bottom of the window. Doing so saves your settings and enables Remote Desktop on your target computer.
Summary: Make sure that you meet the criteria for enabling Remote Desktop. Open Start . Click Control Panel. Set the "View by" option to "Large icons". Click System. Click Remote settings. Check the "Allow Remote Assistance connections to this computer" box. Check the "Allow connections from computers running any version of Remote Desktop" box. Add more users if necessary. Click OK.

In one sentence, describe what the following article is about: To find the missing angle of a triangle using the cosine rule, you need to know the length of all three sides of the triangle. For example, you might have triangle RST. Side SR is 8 cm long. Side ST is 10 cm long. Side RT is 12 cm long. What is the measurement of angle S? The formula is c2=a2+b22abcosC{\displaystyle c^{2}=a^{2}+b^{2}-2ab\cos {C}}. In this formula, cosC{\displaystyle \cos {C}} equals the cosine of the angle you are trying to find. The variable c{\displaystyle c} equals the side opposite the missing angle. The variables a{\displaystyle a} and b{\displaystyle b} are the lengths of the other two sides. Plug these values into the formula. For example, since side RT is opposite the missing angle, angle S, side RT will equal c{\displaystyle c} in the formula. The other two side lengths will be a{\displaystyle a} and b{\displaystyle b}. It doesn't matter which side is which variable. So, your formula should look like this: 122=82+1022(8)(10)cosC{\displaystyle 12^{2}=8^{2}+10^{2}-2(8)(10)\cos {C}}. You are multiplying 2ab{\displaystyle 2ab} times the cosine of the missing angle, which you don't know yet. So, the variable should remain. For example, 122=82+102160cosC{\displaystyle 12^{2}=8^{2}+10^{2}-160\cos {C}}. Remember that to square a number, you multiply the number by itself. For example, 144=82+102160cosC{\displaystyle 144=8^{2}+10^{2}-160\cos {C}} Make sure you square each number first, and then add them together. For example:144=64+100160cosC{\displaystyle 144=64+100-160\cos {C}}144=164160cosC{\displaystyle 144=164-160\cos {C}} To do this, subtract the sum of a2{\displaystyle a^{2}} and b2{\displaystyle b^{2}} from both sides of the equation. Then, divide each side of the equation by the coefficient of the missing angle's cosine. For example, to isolate the cosine of the missing angle, subtract 164 from both sides of the equation, then divide each side by -160:144164=164164160cosC{\displaystyle 144-164=164-164-160\cos {C}}20=160cosC{\displaystyle -20=-160\cos {C}}20160=160cosC160{\displaystyle {
rac {-20}{-160}}={
rac {-160\cos {C}}{-160}}}0.125=cosC{\displaystyle 0.125=\cos {C}} This will give you the measurement of the missing angle. On a calculator, the inverse cosine key is denoted by COS1{\displaystyle COS^{-1}}. For example, the inverse cosine of .0125 is 82.8192. So, the missing angle, angle S, is 82.8192 degrees.
Summary:
