Find the value of x.
please help !!

y = 120

Step-by-step explanation:

Interior angles of a triangle add up to 180°

So,

x+87+33 = 180

x + 120 = 180

Subtracting 120 to both sides

x = 180-120

x = 60°

Now

Angles on a straight line also add up to 180°

So,

x+y = 180

60 + y = 180

Subtracting 60 to both sides , we get

y = 180-60

y = 120

y=mx+

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
