Question

Who can do this question, I don't know how to do...this is difficult for me....who can teach me?

Answer 1

We know that AB and CD are parallel.  This allows many assumptions.
From that we know that angle A and angle D are congruent. 
That means that x + 8 = 2x - 22 and we can solve for x
x + 8 = 2x - 22
x + 30 = 2x
30 = x or x = 30

We know from the figure that angle B is x or now that we solved for x is 30 degrees.  Also, we know that both angle A and angle D are 38 degrees.  Now we can solve for the vertical angle E which has a measure of y degrees.  A triangle has the sum of its angles equal to 180 degrees.

We can set up an equation like this 30 + 38 + y = 180
30 + 38 + y = 180
68 + y = 180
y = 112 degrees

That is how you would solve this problem
