The perimeter of a kite is 52 meters. If one side measures 19 meters find the measure of the opposite side.
Setler [38]

For any kite, we have two pairs of congruent adjacent sides. In general, the kite would have sides of x, x, y , y. In this case, x = 19 is known while y is unknown.

The four sides add up to 52, so

x+x+y+y = perimeter

19+19+y+y = 52

38+2y = 52

2y+38-38 = 52-38 .... subtract 38 from both sides

2y = 14

2y/2 = 14/2 ... divide both sides by 2

y = 7

Therefore the opposite side of the 19 meter side is 7 meters

<h3>Answer: B) 7 meters</h3>

Suppose there is a 1.2°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on
Nesterboy [21]

Answer: 49.7^{\circ}F

Step-by-step explanation:

Given

The temperature on the ground is 56.9^{\circ}F

temperature drop observed is 1.2^{\circ}F\ \text{per 1000 ft}

The height of the plane is  6000\ ft

The total increase in height per 1000\ ft is 6 units

Temperature drop is

\Rightarrow 1.2\times 6=7.2^{\circ}F

The temperature at that altitude is

\Rightarrow 56.9-7.2=49.7^{\circ}F
