The value of x according to the described angles is; 8
<h3>Complementary angles</h3>
If two angles A and B are complementary, it follows that A + B = 90 and Cos A = Sin B.
From the statement above, it follows that;
Collect like terms;
Divide both sides by 3;
x = 24/3 = 8.

Answer: 9 feet below or -9 feet
Step-by-step explanation:
Let us say 0 is the surface of a pond. The turtle started at -2 and then traveled -7 more. We will add these negative values to each other.
-2 + -7 = -2 - 7 = -9
The turtle is now -9, or 9 feet below, the surface of the pond.

Answer:
0.0478
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 135 mm
μ is the population mean = 130 mm
σ is the population standard deviation.
We are given variance = 9
Standard deviation = √variance = √9 = 3
Hence
z = 135 - 130/3
z = 1.66667
Probability value from Z-Table:
P(x<135) = 0.95221
P(x>135) = 1 - P(x<135) = 0.04779
Approximately to 4decimal places = 0.0478
