30 ! in the figure below, angle y and angle x from vertical angles. angle y forms a straight line with the 80° angle and the 60° angle.

write and solve the quetion to determine the measure of angle x.

x = 40°

Step-by-step explanation:

Since y, 80 and 60 form a straight angle then their sum = 180°, hence

y + 80 + 60 = 180

y + 140 = 180 ( subtract 140 from both sides )

y = 40

x and y are vertical angles and thus congruent

x = y = 40°

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
