Please I really need this fast<br><br> Find the values of a and b in the kite below.
Marina CMI [18]

Answer:

a=5, b=15

Step-by-step explanation:

we know that

The figure MNLO is a Kite

so

LO=NO  and MN=LM

we have

LO=7a-14, NO=b+6

7a-14=b+6 -----> equation A

MN=b, LM=3a

b=3a -----> equation B

Solve the system of equations by substitution

Substitute equation B in equation A and solve for a

7a-14=(3a)+6

7a-3a=6+14

4a=20

a=5

Find the value of b

b=3a ----> b=3(5)=15

therefore

a=5, b=15
