One side of a kite is 5 cm less than 2 times the length of another. if the perimeter is 14 cm, find the length of each side of the kite. a) 5 cm, 5 cm b) 4.2 cm, 3.4 cm c) 6.3 cm, 7.7 cm d) 4 cm, 3 cm

D) 4 cm, 3 cm  

Step-by-step explanation:  

Since we know that kite is made of two sets of equal sides.

Let x be the length of one of equal sides and y be length of another side of equal sides.      

We have been given that one side of a kite is 5 cm less than 2 times the length of another. We can represent this information as:

We are also told that the perimeter is 14 cm. We can represent this information as:

From equation (1) we will get,

Substituting this value in equation (2) we will get,

Therefore, length of one side of kite is 4 cm.  

Upon substituting y=4 in equation (1) we will get,

Therefore, the length of another side of kite is 3 cm and option D is the correct choice.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
