Sum of all angles inside of a triangle equal 180 degree

The sum of obtuse angles (the one inside of the triangle, bottom right and the one next to is ) must total 180 degrees

so first I would do the obtuse ones

180 = x +15x-4
180 = 16x - 4
184 = 16x
x = 11.5 degrees

so now I would do the inside triangle angles...tell me what you got

The golden ratio is a solution to a quadratic equation.
Crank

Answer:

Below.

Step-by-step explanation:

a.    Φ^2 − Φ − 1 = 0

Φ2 − Φ = 1

(Φ - 0.5)^2 - 0.25 = 1

(Φ - 0.5)^2 = 1.25

Φ - 0.5 = √(1.25)      (We only take the positive root).

Φ  = 0.5 + √(1.25)

b. I used Completing the square.

c.  Φ is irrational That is it cannot be represented as a fraction a/b and because of this it can only be approximated by a decimal.
