Answer:
answer:c 138°
Explanation:
because one of the angles is 42° this means that B is also 42° because opposite angles are equal
to find out the remaining A and C angles we do
360-42-42=276
because opposite angles here are equal again we just divide 276 by 2 to get angles A and C
276÷2= 138°
so the answer is: C 138°
Answer: No
Explanation: It's the temperature of a surface current that depends on where to go.

Explanation:
Answer:
b. 15% nitrogen, 30% phosphorus, 10% potash (potassium)
Explanation:
The marks on the packages of the fertilizers are telling us what is their content. The system used id the N-P-K ratio. The N-P-K ratio is giving us information about the chemicals from which the fertilizer is made, and the percentage of each of them. N stands for nitrogen, P stands for phosphorus, and K stands for potash (potassium). In this case we have 15-30-10. This will mean that the percentage of nitrogen is 15%, the percentage of phosphorus is 30%, and the percentage of potash (potassium) is 10%, meaning that we have a fertilizer that is high on phosphorus content.
The fertilizer grade 15-30-10 corresponds to 15% nitrogen, 30% phosphorous, and 10% potash (potassium), respectively. These nutrients play crucial roles in plant health, growth, energy storage and transfer, along with various cellular functions. The fertilizer type should be chosen based on the plant's specific needs and the existing nutrients in the soil.
The numbers on a bag of fertilizer, or the fertilizer grade, represent the percentages of Nitrogen (N), Phosphorous (P), and Potassium (K), respectively. So, in the case of a 15-30-10 fertilizer, the correct combination would be b. 15% nitrogen, 30% phosphorous, 10% potash (potassium).
Nitrogen is crucial in many of a plant’s biological processes and is a major component of proteins, nucleic acids, chlorophyll, and other cell components. Phosphorus helps plants store and transfer energy. Potassium, also known as potash, is important for overall plant health due to its role in the functioning of cell membranes and its involvement in photosynthesis as well as other cellular processes.
Thus, the composition of a fertilizer should be tailored to the nutritional needs of the specific plant and the nutrient content of the soil in which it is being grown.
