Answer:

a = 4

Step-by-step explanation:

Assuming you require to find the value of a

In a rhombus all the sides are congruent, thus

9a - 13 = 3a + 11 ( subtract 3a from both sides )

6a - 13 = 11 ( add 13 to both sides )

6a = 24 ( divide both sides by 6 )

a = 4

Then

XW = 9a - 13 = 9(4) - 13 = 36 - 13 = 23

Thus the sides of the rhombus are 23 units

A hawk takes flight from a mountain peak and flies 800 meters west. Then it takes a turn and flies 200 meters south. What is the
Katena32 [7]

Answer:

the hawk has flow 824.62 meters southwest of the mountain peak.

Step-by-step explanation:

In order to find the distance we need to use the Pythagoras theorem

d^2 = 800^2 + 200^2

d= 824.6 m

we can find the direction by using the eq for a tangent

he opposite side is 200 m and the adjacent side is 800m

tan theta = opposite / adjacent

theta = arc tan (800/200)

The hawk is at a distance of 824.6m flying at an angle 76 degrees NE of the mountain peak.

The final location will be southwest of the mountain peek.

a2+b2=c2

a = 200

b= 800

c = √(2002+8002) = 824.62

So the hawk has flow 824.62 meters southwest of the mountain peak.

The length of a chord is equal to its distance to the center of the circle. A second chord in the same circle is twice as long a
Rama09 [41]

Answer:

The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.

Step-by-step explanation:

The length of the chord AB is the same as the distance OC from the center to the cord. Let OC=2x, then CA=x. By the Pythagorean theorem, the radius r of the circle is

r^2=OC^2+AC^2,\\ \\r^2=(2x)^2+x^2=5x^2,\\ \\r=\sqrt{5}x.

The length of the arc ED is 4x.

Consider right triangle EFO. In this triangle, EF=2x, EO=r, then the distance OF is

OF^2=OE^2-EF^2,\\ \\OF^2=5x^2-(2x)^2=x^2,\\ \\OF=x.

The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.
