Find the value of x and y
bagirrra123 [75]
According to google, the red marks mean those two lines are the same length.  If that's the case, we know that x is the angle in both corners of the lower triangle.  We also know that because the angle of a straight line is 180, that the top angle of the bottom triangle is 140, because it's divided into two parts, one of which is 40.  That leaves 140 for the rest.  Now we know that there are 180 degrees in a triangle so x=(180-140)/2 = x=20degrees.
The right angle in the left corner is 90 degrees.  It is divided in two parts, the lower one of which we just found to be 20.  So the other part must by 70deg.
So for the upper angle y, we have 180-70-40= y=70degrees

Please help i dont get it
raketka [301]

<em>x</em> and <em>w</em> are parallel lines, so

• angles 2 and the one labeled 75º are congruent because they are alternating interior angles, and

• angles 1 and 2 are supplementary because they form a linear pair.

The first observation tells you that angle 2 has measure 75º, and angle 1 has measure <em>m</em> such that

<em>m</em> + 75º = 180º

so angle 1 has measure 180º - 75º = 105º.

If each acute angle of a parallelogram measures 59 degrees, then what is the masure of each obtuse angle?
xenn [34]
A parallelogram has to have a total of 360 degrees in angles, so we take 59 x 2 to get 118, we then subtract 118 from 360, 360 - 118 =  242, we then divide by two because a parallelogram has 2 obtuse angles, giving us an answer of 121 degrees. Hope this helps
