How to find the length of the unknown shorter side?
This gives the formula for finding the length of the unknown shorter side when the hypotenuse and the other shorter side are known: Top Tip Leaving the Answer as a Square Root To find the side, a, you have to find the square root of a2. Unless a2is a square number, a will not be a whole number.
How to calculate the length of a side?
Start with the formula: a = √(c2− b2) Don’t forget:√ means square rootandc2= c × c (c squared), b2= b × b. 2 Find the lengths of the sides from the right triangle. In our example, the known side lengths are b = 6 and h = 10. 3 Substitute b = 6 and c = 10 into the formula. a = √(102− 62) = √((10 × 10) − (6 × 6)) c= √(100 − 36) = √64 a = 8 Answer:
How to tell if a calculator is in degrees or radian mode?
To figure out if your calculator is in degrees or radians mode, try finding the sin (30). If your calculator gives a result of 0.5, it is in degrees mode, and if you get -.988031, it is in radian mode and you need to switch it!
How to find the shorter side of a triangle?
The Lesson The length of a shorter side of a right triangle (called a leg or cathetus) can be found from Pythagoras’ theorem, if the length of the hypotenuse and another side is known. The length of the side is is found using the formula: In the formula, a and b are the lengths of the shorter sides and c is the length of the hypotenuse.
How can I find out the size of my a / C unit?
First, measure the length and width of the room or rooms to be cooled. Most of time, you can find the square footage of your entire home in your mortgage paperwork or property tax statements, which will save you from having to re-calculate. If you do need to get out the tape measure, remember not to include your basement, attic space, or closets.
What happens if your a / C unit is too big?
If you have one that is too big, it can waste a lot of energy and cause humidity problems in your home; however, one that’s too small can make everyone inside miserable during those hot summer months. So, how do you know if your A/C is big enough?
How to tell the difference between high and low suction pressure?
PROBLEM DIAGNOSIS CAUSE AND REMEDY SYMPTOM AND INSPECTION REPAIR OR REPLACE IMPROPER COOLING – (No unusual compressor noise) High suction pressure, low discharge pressure 1. Inspect valve plate, reed and gasket areas Replace valve plate and gaskets Low suction and discharge pressure 1. Check for low refrig. charge 2. Refer to service manual 3.
How to calculate side a using the law of cosines?
To calculate side a for example, enter the opposite angle A and the two other adjacent sides b and c. Using different forms of the law of cosines we can calculate all of the other unknown angles or sides. This is the same calculation as Side-Angle-Side (SAS) Theorem .
