Answer:
Step-by-step explanation:
The sin(30) = 1/2
The sin(30) = 1/2 = opposite / hypotenuse
Opposite = 7
hypotenuse = opposite / sin(30)
hypotenuse = 7 / (1/2) = 7 *2 / 1 = 14
The long side can be found using the Pythagorian Theorem.
a^2 + b^2 = c^2
a = 7
b = ?
c = 14
14^2 = 7^2 + b^2
196 - 49 = b^2
147 = c^2
147 = 3*7 *7
sqrt(b^2) = sqrt(3*7*7)
b = 7 sqrt(3)
Answer:
-( 2x^2+6-4/x)
that what i got when you divide
Perimeter: P=24 ftLenght: LWidth: W
The length is 2 ft longer than the width:(1) L= W+2 ft
Perimeter: P=2(W+L)P=24 ft2(W+L)=24 ftDividing both sides of the equation by 2:2(W+L)/2 =(24 ft)/2(2) W+L=12 ft
We have a system of 2 equations and 2 unkowns:(1) L=W+2(2) W+L=12
Using the method of substitution: Replacing L by W+2 in the second equation:(2) W+L=12W+(W+2)=12W+W+2=122W+2=12
Solving foe W2W+2-2=12-22W=10Dividing both sides of the equation by 2:2W/2=10/2W=5
Replacing W by 5 in the first equation:(1) L=W+2L=5+2L=7
Answers:What is the width? 5 ftWhat is the length? 7 ft
