Answer:
67%
Step-by-step explanation:
Cost plus markup = selling price.
Here, the cost was $30 and the selling price was $50. Subtracting $30 from $50, we get $20, which was the dollar amount of the markup.
We now compare this $20 to the original cost ($30):
$20
------- * 100^ = 67%
$30
The markup, as a percentage, was 67%.

Angle opposite to the required length:
180 - 90 - 43 = 47°
X/sin47 = 6.5/sin43
X = sin47 × 6.5/sin43
X = 6.970396615
