Solve the question below 66
4vir4ik [10]

Answer:

we get the value of x: x = 39.1

Step-by-step explanation:

We are given:

Base = 19

Hypotenuse = x

and Angle = 62°

We need to find value of x.

We know that: cos\theta=\frac{Base}{Hypotenuse}

Putting values and finding value of x

cos\theta=\frac{Base}{Hypotenuse}\\cos\: 61=\frac{19}{x} \\0.4848=\frac{19}{x}\\x(0.4848)=19\\x=\frac{19}{0.4848}\\x=39.1

So, we get the value of x: x = 39.1

A box has rectangular top, bottom, and sides. The top and bottom are square. The volume must be 7 cubic meters. Express the tota
SVEN [57.7K]

Answer:

Step-by-step explanation:

Given

Box has top and bottom as  square

Volume =7 m^3

let l ,b ,h be length, breadth and height of box

l=b because top and bottom as square

thus volume =b^2\cdot h

b^2=\frac{7}{h}

Total surface area(TSA)=2\left ( lb+bh+hl\right )

TSA=2\left ( b^2+bh+bh\right )

TSA=2\left (  b^2+2bh\right )

TSA=2\left ( \frac{7}{h}+2h\times \sqrt{\frac{7}{h}}\right )

TSA=2\left ( \frac{7}{h}+2\sqrt{7h}\right )
