Answer:
Step-by-step explanation:
Firstly we've to find the hypotenuse of the first triangle:
<u>In the first triangle, for the angle 45: </u>
Adjacent = 10
Hypotenuse = ?
Using cos for it.
Cos 45 = adjacent / hypotenuse
0.707 = 10 / hyp
hyp = 10 / 0.707
hyp = 14.14
The hypotenuse of the first triangle is actually the base (or opposite) of the triangle.
Also, hypotenuse = x and angle is 60 degrees.
<u>So, we will use the sin ratio.</u>
sin 60 = opposite / hypotenuse
0.866 = 14.14 / x
x = 14.14 / 0.866
x = 16.3
Hope this helped!

Answer:
The area of the deck after she doubles the length and width will be of 384 square feet.
Step-by-step explanation:
Area of a rectangle:
The area of a rectangle of length l and width w is given by:
Doubling length and width:
If we double the length and the width, the dimensions are 2l and 2w. Thus, the area will be of:
That is, if both dimensions are doubled, the area is multiplied by 4.
What will the area of the deck be after she doubles the length and width?
Was 96. Then, both dimensions were doubled, and the area has to be multiplied by 4.
96*4 = 384
The area of the deck after she doubles the length and width will be of 384 square feet.
Answer:
- ∞ < y < ∞
Step-by-step explanation:
The given function is, .
Now, the origin function of this above function is, which has real y-values as output for all real x-values input.
Hence, the function will ba valid for all real values of x and will have real y-value corresponding to each x-value.
Therefore, the range of this function i.e. the y-value of this function will be
- ∞ < y < ∞. (Answer)
