A park maintenance person stands 19 m from a circular monument. If you assume her lines of sight form tangents to the monument and make an angle of 34°, what is the measure of the arc of the monument that her lines of sight intersect? 146 124 112 56
@welshfella i think it is either a or d
sorry cant help with arcs - never did them in school I'll have to educate myself in arcs

|dw:1431274172334:dw| x = (a+b)/2 BUT, one of these angles is "negative" with respect to the angle. what is a negative arc? |dw:1431274243877:dw|
but it might be simpler than this ... the sum of the angles of a quadralateral add up to what? |dw:1431274319037:dw| the tangents take up 90 and 90, so the remaining 2 angles add up to what?
