Since there are 2 congruent angles that means that you can set up the equation to equal to 180. 7x+8+7x+8+7x=180, 21x+16=180, 21x=164, x=7.81

Answer:

θ = 60.34

Step-by-step explanation:

$\frac{\left(12.8\cdot \:sin\left(90\right)\right)}{sin\left(52.3\right)}$ = 16.177

$\frac{\left(16.177\cdot \:sin\left(90\right)\right)}{18.6}$ = θ = .869

$arcsin\left(.869\right)$ = 60.34
