Since the triangle is equilateral, QR = RS = QS.
a. MS = (1/2)74
MS = 37
b. Half of the equilateral triangle makes a right triangle. Use Pythagorean Theorem to find QM.
a^2 + b^2 = c^2
37^2 + b^2 = 74^2
1369 + b^2 = 5476
subtract 1369 from both sides
b^2 = 4107
take the square root if both sides
b = 64.1
QM = 64.1
Answer:
3
Step-by-step explanation:
$x @ 4%, $x/3 @ 5% , $(10,000- 4x/3) @ 9%
<span>.04x +.05x/3 + .09(10000 - 4x/3) = 729 </span>
<span>4x + 5x/3 + 9(10000 - 4x/3) = 72900 </span>
<span>19x/3 = 17100, x = 2700 </span>
<span>------------------ </span>
<span>$2700 @ 4% </span>
<span>$900 @ 5% </span>
<span>$6400 @9% </span>
