Answer:

Remember:

Triangle area= \frac{b*h}{2}

h of equilateral triangle = \frac{\sqrt{3}}{2}*a

Step-by-step explanation:

b=4yd

a=4yd

h = \frac{\sqrt{3}}{2}*a

h = \frac{\sqrt{3}}{2}*4yd

4/2=2

h= 2\sqrt{3} yd

area= \frac{b*h}{2}

area= \frac{4 yd*2\sqrt{3} yd}{2}

2/2=1

Finally

area= 4\sqrt{3} yd^2

Answer:

The first one. 4 times square root of 3.

Step-by-step explanation:

The side of the equilateral triangle that represents the height of the triangle will have a length of because it will be opposite the 60o angle. To calculate the area of the triangle, multiply the base (one side of the equilateral triangle) and the height (the perpendicular bisector) and divide by two.

rusak2 [61]

Answer:

The distance between the astronomers and the moon was 7.56*10^{8] meters.

Step-by-step explanation:

We have that the speed is the distance divided by the time, so:

v = \frac{d}{t}

In this problem, we have that:

The reflected laser beam was observed by the astronomers 2.52 s after the laser pulse was sent. This means that t = 2.52.

If the speed of light is 3.00 times 10^8 m/s, what was the distance between the astronomers and the moon?

We have that v = 3*10^{8}m/s.

We have to find d. So:

v = \frac{d}{t}

d = vt

d = 3*10^{8}*2.52

7.56*10^{8]

The distance between the astronomers and the moon was 7.56*10^{8] meters.
