Let's start by identify a 30-60-90 triangle

If we compare those two traingles we can stablish the following relation:

\begin{gathered} a\sqrt[]{3}=6\sqrt[]{3} \\  \end{gathered}

Therefore, a=6

u is the opposite side to the 90° angle, therefore

\begin{gathered} u=2a \\ u=2\cdot6 \\ u=12 \end{gathered}

on the other hand, v is the opposite side to the 30° angles, so

\begin{gathered} v=a \\ v=6 \end{gathered}

Equation : (7x-4)+(3x-3)+(x) = 180
In the equation the sum of the internal angle in the triangle is 180 degrees. Use this equation to figure the sum of angle in any quadrilateral 180*(number of sides-2)
Solve the equation
Put all similar variable on one side
7x+3x+x-4-3=180
11x-7=180
11x=180+7
11x=187
x = 187/11
x = 17
Now find the angles by plugging in x
Angle F (7*17-4) = 115 degrees
Angle G (x) = 17 degrees
Angle E (3*17-3) = 48 degrees
If you add 115+48+17 you will get a sum of 180 this shows your answer is right


Angle F = 115
Angle G = 17
Angle E = 48
