a. What was the approximate temperature at a depth of 70 m? At the surface?
26° C
b. At what depth was the temperature a little more than 27°C?
40 m
c. Do the points in the scatter plot show a relationship? Explain your thinking.
Yes, the scatter plot show a relationship between the depth and the temperature of Lake Turkana. It shows a negative correlation between the two variables. The deeper the lake is, the cooler the temperature .

Answer:
50
Step-by-step explanation:
x = √30² - 18² = √576 = 24
tan A = 18/24 = 3/4
∠A = ∠B
tan B = tan A = 24 / y = 3 / 4
y = (24 x 4) / 3 = 32
Z = y + 18 = 32 + 18 = 50
