6. Find the value of x.
I 5x+ 2
6x + 4
122 - 4
H
J P

Step-by-step explanation:

sum of two interior angles is equal to one exterior anglethis implies that,

(6x+4) +(5x+2)= 12x-4

11x+6=12x-4make X the subject

11x-12x=-4-6

-x= -10divide both sides by -1

x=10

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
