In the figure above, DA || BC and AB bisects DAC. What is the measure of BCA in terms
of a?
A) 180-a
B) 2a-180
C) 180 - 2a
D) 2a-90

c. 180-2a

Please tell me if I am wrong.

Step-by-step explanation:

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
