Answer:

6.4 cm

Step-by-step explanation:

Area of triangle = 17.28 cm²

\frac{1}{2}*base *altitude = 17.28\\\\\frac{1}{2}*base*5.4=17.28\\\\base = 17.28*\frac{2}{5.4}\\\\base= 3.2*2\\\\base = 6.4 cm

Question 1(Multiple Choice Worth 5 points)
Nadusha1986 [10]

Answer: arc\ length =13.19cm

Step-by-step explanation:

You need to use the following formula:

arc\ length=r\theta

Where "r" is the radius and \theta is is the central angle of the arc in radians.

Assuming that that the angle \frac{3\pi }{5} is the central angle of the arc, and knowing that the radius is 7 centimeters, you can substitute values into the formula.

Therefore, you get:

arc\ length=r\theta\\\\arc\ length= (7cm)(\frac{3\pi}{5})}\\\\arc\ length =13.19cm

<h3>"The answer is the yellow lines in the attached figure. </h3>

Step-by-step explanation: As shown in the attached figure, regular hexagon FGHIJK and square ABCD shares common centre on the co-ordinate plane and AB || FG.

We are to find the line across which the combined figure will reflect onto itself.

In the attached figure, we see two lines which are yellow in colour. We can easily detect that the figure will be reflected onto itself if these two lines acts as a mirror separately.

Hence these yellow lines are the required lines."
