Answer:

55.74

Step-by-step explanation:

Since the culture was tested and then the countdown started, you need to multiply the initial value by 3.5. Since it is tested once every 15 minutes, it will be tested two more times by the time 30 minutes is up; a total of 3 times tested.

1.3 x 3.5 = 4.55

4.5 x 3.5 = 15.925

15.925 x 3.5 = 55.7375

$\angle{DBC }$ =(5x+4)°

$\angle{ A }$ =(2x-2)°

$\angle{C }$ =(4x-6)°

we know that,

$\angle{DBC}$ = $\angle{A}$ + $\angle{C}$

According to the question,

$\tt{ 5x+4=2x-2+4x-6 }$

$\tt{ 5x+4=6x-8 }$

$\tt{ 6x-5x=4+8 }$

$\blue{x=12 }$

so,

$\angle{C }$ =(4x-6)°=(4×12-6)°=(48-6)°=42°
