Weights The dosage chart below was prepared by a drug company for doctors who prescribed Tobramycin, a drug that combats serious bacterial infections such as those in the central nervous system, for life- threatening situations. Weight (pounds) 88 99 110 121 132 143 154 165 176 187 198 209 Usual Dosage (mg) 40 4. Write the equations of the two lines. 45 50 55 60 65 70 75 80 85 90 95 1. Use grid paper to plot the data (weight, usual dosage) and draw a best-fit line. 2. Plot (weight, maximum dosage) on the same axes. Draw a best-fit line. 3. Find the slope for each line. What do they mean, and how do they compare? Maximum Dosage (mg) 66 75 83 91 100 108 116 125 133 141 150 158 5. Are the two lines parallel? Why or why not? 6. Use a graphing calculator to plot (usual dosage, maximum dosage). Use the calculator to construct a regression line for this data set. How does this line compare to the two lines found in 1 and 2?​

Answer 1

Answer: Third angle = 180° - (47° + 48°)

Third angle = 180° - 95°

Third angle = 85°

Explanation:

Now that we know all three angles, we can classify the triangle based on the measures of its angles.

- If all three angles are less than 90°, the triangle is classified as an acute triangle.

- If one angle is greater than 90°, the triangle is classified as an obtuse triangle.

- If one angle measures exactly 90°, the triangle is classified as a right triangle.

In this case, since all three angles (47°, 48°, and 85°) are less than 90°, the triangle is classified as an acute triangle.

Therefore, the triangle with one angle measuring 47° and another angle measuring 48° is classified as an acute triangle.
