2. A square-based tent has the cross-sectional
ollegr [7]

(a) Length of the height is 2.732 m

(b) Length of the base is 5.466 m

<u>Explanation:</u>

An image is attached for reference.

(a)

In ΔAOB,

sin 30^o = \frac{AO}{AB} \\\\0.5 = \frac{AO}{2} \\\\AO = 1 m

In ΔBGD,

sin 60^o = \frac{BG}{BD} \\\\0.866 = \frac{BG}{2} \\\\BG = 1.732 m

According to the figure, BG = OE = 1.732 m

Height of the tent, AE = AO + OE

                                  = 1 m + 1.732 m

                                  = 2.732 m

(b)

DF = ?

In ΔAOB,

tan 30^o = \frac{AO}{OB} \\\\0.577 = \frac{1}{OB} \\\\OB = 1.733 m\\\\\\

According to the figure, OB = GE = 1.733 m

In ΔBGD,

tan 60^o = \frac{BG}{DG} \\\\1.732 = \frac{1.732}{DG}\\ \\DG = 1m

According to the figure, DE = DG + GE

                                      DE = 1 m + 1.733 m

                                     DE = 2.733 m

Length of the base, DF = 2 X DE

                              DF = 2 X 2.733 m

                               DF = 5.466 m

what is fourteen less than five times a number is three times the number and what is twelve more than seven times a number equal
andrey2020 [161]
If I am reading the equations correctly, they are:
   5x - 14 = 3x   AND  7x + 12 = x - 6

If this is correct, the first one would be worked out like this:
   5x (- 5x) - 14 = 3x (- 5x)
   - 14 = - 2x
   - 14 (/ - 2) = - 2x (/ - 2)
   7 = x

The second would be worked out like this:
    7x + 12 (+ 6) = x - 6 (+ 6)
    7x + 18 = x
    7x (- 7x) + 18 = x (- 7x)
    18 = - 6x
    18 (/ - 6) = - 6x (/ - 6)
    - 3 = x

I hope this is what you are looking for :)
