Can some one help me understand this???

so the value of x is the degree its at same for y if that makes any sense

Step-by-step explanation:

x=40 y=140

Step-by-step explanation:

To work out x:

The angles in a triangle always add up to 180.

You already have one angle which is 50 the bottom left angle is a right angle and right angles always equal 90. To work out x, do 50+90=140 then do 180-140=40.

To work out y:

Angles on a straight also add up to 180.

So as you have figured out what x is (40) you would take it away from 180 to give you y.

180-40=140

Hope this helps :)

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
