Hello :
the discriminat of each quadratic equation : ax²+bx+c=0 ....(a <span>≠ 0) is :
</span><span>Δ = b² -4ac
1 ) </span>Δ > 0 the equation has two reals solutions : x = (-b±√Δ)/2a
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ <span>< 0 : no reals solutions</span>

Step-by-step explanation:
the two opposites Angles of this quadrilateral are equal, again the angles should sum up to 360
t-9+t-91+t-16+t+25=360
4t=360-101
4t=259
t=64.75
