Answer:
5x² - 20x
Step-by-step explanation:
multiply each term in the parenthesis by the 5x outside
5x(x - 4)
= (5x × x ) + (5x × - 4 )
= 5x² + (- 20x) = 5x² - 20x

Step-by-step explanation:
Given
Let the three sides be represented with A, B, C
Let the angles be represented with
[See Attachment for Triangle]
What the question is to calculate the third length (Side B) and the other 2 angles ()
Solving for Side B;
When two angles of a triangle are known, the third side is calculated as thus;
Substitute: , ;
Take Square root of both sides
<em>(Approximated)</em>
Calculating Angle
Substitute: , ;
Subtract 180 from both sides
Divide both sides by -144
Take arccos of both sides
<em>(Approximated)</em>
Calculating
Sum of angles in a triangle = 180
Hence;
Make the subject of formula
