3.2 worksheet angles

x = 28,  y = 23

Step-by-step explanation:

in keeping with working only with the expressions which have the variable 'y'

the 3y angle forms a linear pair with the angle which is corresponding to the 5y-4 angle

therefore, we can say that 5y - 4 = 180 - 3y

solve for 'y':   5y - 4 = 180 - 3y

                      8y = 184

                       y = 23

Substitute to find measure of angle 5y-4:  5(23) - 4 = 111 degrees

Now we know that 2x + 13 has to equal 180 - 111 or 69 degrees

solve for 'x':  2x + 13 = 69

                     2x = 56

                     x = 28

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

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.
