Answer:

220

Step-by-step explanation:

We need to find the 3rd side length

We already know the hypotenuse and one side, so we can use the Pythagorean formula.

101^2 = a^2 + 20^2. A is the third side, and solving for it, we find that it equals 99.

Side 1 = 101

Side 2 = 99

Side 3 = 20

101 + 99 + 20 = 220

How do you find a missing side with trigonometry
Nata [24]
Example 1:  The angle is 42 deg and the length of the hypotenuse is 25.  The side of length x is opposite the 42 deg angle.  
                                opposite side
Thus, sin 42 deg = --------------------  =>  25 sin 42 deg = x = opp side
                                         25

                                                                25(0.669) = 16.7 units (answer)

When p2 – 4p is subtracted from p2 + p – 6, the result is 5p-6 To get p – 9, subtract
jeka57 [31]
(p^{2}  + p - 6) - (x) = p - 9&#10;&#10; is what is asked.

So all you need to do is a value that will result to p - 9.

x = (p^{2} + p - 6) - p + 9  To isolate x we just transpose the values from the other side of the equation and do the opposite operation. 

Combine like terms and just copy the terms that do not have similar expressions:

p will cancel out because p - p = 0
-6 and + 9  will come together because they are like terms: -6 + 9 = 3 
p^{2} does not have a pair so it will remain as is. you will be left with:

p^{2}  + 3

Let us check:

   p^{2} + p - 6
-  p^{2} + 0 + 3  
----------------------------
   0 + p - 9    or p -9
