Answer: $42.60
Step-by-step explanation:
Original price: p
Discount: 30%
Sale price: 29.82
p x 0.7 = 29.82
p = 29.82/0.7 = 42.60
Answer:
The correct answer is 47 degrees.
Step-by-step explanation:
Use cosine.
cos(x)= adj/hyp
cos(x)=19/28
x=arccos(19/28)
Use a calculator
x is approximately 47 degrees.
All the angles required to complete each sentence are:
- m ∠ 4 = 60, m ∠ 2 = 120
- m ∠ 3 = 110, m ∠ 4 = 70
- m ∠ 2 = x, m ∠ 1 = 180 - x
<h3>How to find measures of missing angles by Euclidean geometry</h3>
In this question we must take advantage of definitions and theorems of Euclidean geometry to complete the three sentences seen in the figure. Now we proceed to present each sentence completed in detail:
- If m ∠ 5 = 60, then m ∠ 4 = 60 by <em>alternal internal</em> angles between <em>parallel</em> lines and m ∠ 2 = 120 by <em>supplementary</em> angles.
- If m ∠ 7 = 110, then m ∠ 3 = 110 by <em>corresponding</em> angles between <em>parallel</em> lines and m ∠ 4 = 70 by <em>supplementary</em> angles.
- If m ∠ 6 = x, then m ∠ 2 = x by <em>corresponding</em> angles and m ∠ 1 = 180 - x by <em>supplementary</em> angles.
