Answer:
Step-by-step explanation:
Yuan earned $336.3457.
You are asked to round this number to the nearest hundredth, that is, so there are only two digits after the decimal.
$336.34|57
A rule in rounding numbers is: if the first figure to be dropped is 5 with any nonzero digits following it, then the last figure kept should be rounded up (increased by 1).
The number becomes $336.35.
The measure of the angle m∠Q is 30.8 degree after applying the law of cosine.
<h3>What is the triangle?</h3>The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
Let's suppose the angle m∠Q is A
So applying law of cosine:
CosA = 0.859
A = 30.75 ≈ 30.8 degree
Thus, the measure of the angle m∠Q is 30.8 degree after applying the law of cosine.
