Question

PQ is a straight line. Work out the value of y

Answer 1

Answer:

y = 68   because of the equation 2y + (y - 24 ) = 180,  Angle Sum postulate

Step-by-step explanation:

Because line  PQ is a straight line,  we see it measures 180 degrees.

So that means  2y + (y - 24)  =  180 degrees.

Those two angles add up to 180 degrees.

so we can solve this equation for y now.

2y + (y - 24) = 180

3y - 24 = 180

3y = 180 + 24

3y = 204

y = 204/3 = 68

That is how y = 68.

Then the 2*y = 2*68 = 136 degrees.

and  the other angle y - 24 = 68 - 24 = 44 degrees.

Answer 2

Answer:

b- 68

Step-by-step explanation:

2(68)= 136

68-24=44

136+44= 180
