A^2+b^2=c^2 (Pythagoran theorem)
-> 30^2 + length^2 = 78^2
-> length = √6084-900 = <span>√5184 = 72 ft
=> area = length x width = 72 x 30 = 2160 ft^2</span>
You can use two variables in an equation, just substitute it in.
In trigonometric ratios, the cos (x) = adjacent over hypotenuse.
Therefore, in the diagram, cos (55°) = s/q
To isolate q, divide both sides by s
cos (55°) / s = 1/ q
Then flip both numerators and denominators (raise both sides to the power of -1)
q = s / cos (55°)
Answer is D
Answer:
16
Explanation:
In your parent 30 60 90 triangle, you will see that the larger leg is x times the square root of three while the shorter leg is just x, that means you would divide the longer leg by the square root of three which gives you 16 in this question.
