4 angles = 360

120 + 117 +55 = 292

360-292 = 68

4th angle = 68 degrees

Answer:

$t_{1} \approx 9.943\,s$ and $t_{2} \approx 0.057\,s$

Step-by-step explanation:

The following polynomial is needed to be solved:

$-16\cdot t^{2} + 160\cdot t - 9 = 0$

The roots are found by means of the General Equation for Second-Order Polynomials:

$t_{1} \approx 9.943\,s$ and $t_{2} \approx 0.057\,s$

Physically speaking, both solutions are reasonable.
