Answer:
cos(X) = 40/41, sin(X) = 9/41, tan(X) = 9/40
Step-by-step explanation:
Know the acronym SOHCAHTOA: Sine is the Opposite side divided by the Hypotenuse, Cosine is the Adjacent side divided by the Hypotenuse, and Tangent is the Opposite side divided by the Adjacent side.
I believe it would be C, if I'm not mistaken.1 yard = 3 feet
You'd have to divide by yards
4.6 yards = 3 feet = 13.8 feet
yard
Sorry if this doesn't help
Answer: 8/9 or .8
Advice for the future, use math w a y next time for stuff like this.
Answer:
(13 + x) * (15 + x) = 390ft²
18.8 feets ; 20.8 feets
Step-by-step explanation:
Given that:
Initial dimension of patio :
Length (L) = 13 feets
Width ( W) = 15 feets
Initial Area of rectangle :
Length * width = 13 * 15 = 195 feets²
To double the initial area of rectangle :
2 * 195 ft² = 390 ft²
Hence, area of proposed patio = 390ft²
Area of proposed patio:
(13 + x) * (15 + x) = 390ft²
195 + 13x + 15x + x² = 390
x² + 18x - 195 = 0
Using the quadratic equation solver:
X = - 33.77 = - 33.8 or
X = 5.77 = 5.8
X cannot be negative,
Hence, x = 5.8
Length and width of new patio:
Length = 13 + x = 13 + 5.8 = 18.8 feets
Width = 15 + x = 15 + 5.8 = 20.8 feets
