Triangle angle sum theorem What is the value of p?
1 answer:
The angle sum property of triangle states that the sum of all angles of a triangle should be equal to 180°...
According to this theorem,
<em>The value of </em><em>p</em><em> is </em><em>97</em><em>... </em>
Now, Let's find the value of all angles with the help of value of p
- Angle 1 = 54°
- Angle 2 = p-48 = 97-48 = 49°
- Angle 3 = p-20 = 97-20 = 77°

Expand both factors and collect like term
Using Pascal' triangle with n = 6 to obtain the coefficients
1 6 15 20 15 6 1
Decreasing powers of 1 from to
Increasing powers of 3x from to
= 1. + 6.
+ 15.
+ 20.
+ 15.1²
+ 6.
+ 1.
= 1 + 18x + 135x² + 540x³ + 1215 + 1458
+ 729
--------------------------------------------------------------------------------------
= 1. + 6.
+ 15.
+ 20.
+ 15.1²
+ 6.
+ 1.
= 1 - 18x + 135x² - 540x³ + 1215 - 1458
+ 729
----------------------------------------------------------------------------------
Collecting like terms from both expressions
+
= 2 + 270x² + 2430 + 1458

Using Pascal's triangle with n = 5
1 5 10 10 5 1
Decreasing powers of 1 from to
Increasing powers of 2x from to
= 1. + 5.
+ 10.
+ 10.
+ 5.
+ 1.
= 1 + 10x + 40x² + 80x³ + 80 + 32
