Find x. (Hint: Draw an auxiliary line.)

The measure of angle x from the given diagram is 130 degrees
Find the diagram attached
<b and 100⁰ are supplementary i.e they sum up to 180 degrees as shown:
<b + 100 = 180
<b = 180 - 80
<b = 80 degrees
Get the measure of angle "x"
x = <a + <b
x = 50 + 80
x = 130 degrees
Hence the measure of angle x from the given diagram is 130 degrees
