Answer:
Hypotenuse = 14 inches
Adjacent = 12.12 inches
Step-by-step explanation:
Using SOH, CAH TOA Method
According to SOH
Sin(theta) = Opposite/Hypotenuse
Given theta = 30°
Opposite = 7 inches
Sin30° = 7/Hypotenuse
Hypotenuse = 7/Sin30°
Hypotenuse = 7/0.5
Hypotenuse = 14 inches
The other leg will be the adjacent saying x using Pythagoras Theorem to get x
Hypotenuse^2 = Opposite^2 + Adjacent^2
14^2 = 7^2 + x^2
x^2 = 14^2 - 7^2
x^2 = 196 - 49
x^2 = 147
x = sqrt of 147
x = 12.12 inches
To be honest choice whatever you want but my advice is to choose the LED light bulb.
Answer: $397.9
Step-by-step explanation:
First you need to find 65% and 8% of 230
<em>(230 x 65) / 100 = 149.5</em>
<em>65% of 230 is 149.5</em>
<em />
<em>(230 x 8) / 100 = 18.4</em>
<em>8% of 230 is 18.4</em>
Add 230 to the 65% and 8% markups to get the total retail cost
<em>230 + 149.5 + 18.4 = 397.9</em>
The total retail cost of the tent it $397.9
