2.5% of 129,500 is
$129500 * 0.025 = $3237.50 is the commission on the sale
(19)
sales $3012
commission 3.5% of sales: 0.035 * 3012 = $105.42
Raquelle's total earnings: $290 + 105.42 = $395.42
Let us prove that angle 1 is complementary to angle 3 step by step.
1. We have been given that angle 1 is complementary to angle 2.
2. Since we know that complementary angles add up to 90 degrees, therefore, by the definition of complementary .
3. We have been also given that line segment BD bisects .
4. By the definition of bisect .
5. Angles are congruent if their measures, in degrees, are equal, therefore, by angle congruence postulate .
6.
Upon substituting in above equation we will get,
Therefore, by substitution property of equality .
Hence, proven that angle 1 is complementary to angle 3.
Answer:
The angle between the 190 ft. side and the 330 ft. side is
Step-by-step explanation:
<u>The Law of Cosines</u>
When we know the value of all sides of a triangle, we can compute all of its interior angles by using the Law of Cosines, which is a generalization of the Pythagoras's theorem. If a,b, and c are the known sides of a triangle and is the angle formed by sides a and b (opposite to c), then
We'll use the values a=190, b=330, c=280 because we want to compute the angle opposite to c
