x = 80 ° because the 100° angle is vertically opposite b. that means angle b is also 100°. a full circle adds up to 360 and 100+100 = 200. that means the other 2 is 80° each. angle f is in the same position as angle b which means that is also 100° which means it is the same situation. therefore, x=80°
