Answer:
30°
Step-by-step explanation:
Solve the blank angle for the bottom triangle. The sum of all the angles of a triangle is equal to 180. 75° + 75° = 150°. 180° - 150° = 30°. The missing angle of the bottom triangle is 30°. Angle x is equal to the blank angle of the bottom triangle. Therefore, x = 30°.

The length of the colony is the product of 5. 3 × 10^3 and the length of the bacteria
The total length of the colony is 143.1 mm
<h3>How to determine the length of the colony?</h3>
The given parameters are:
Bacteria = 2.7 × 10^–2 mm.
Colony = 5. 3 × 10^3 of the bacteria
So, the length (L) of the colony is:
Rewrite as:
Evaluate the products
Evaluate the product
Hence, the total length of the colony is 143.1 mm
