WebYou should think about the "before" quantity (even though it is not given in the question) Find the percentage change as a multiplier, p (the decimal equivalent of a percentage change) a percentage increase of 4% means p = 1 + 0.04 = 1.04. a percentage decrease of 5% means p = 1 - 0.05 = 0.95. Use "before" × p = "after" to write an equation. WebOur first circle theorem here will be: tangents to a circle from the same point are equal, which in this case tells us that AB and BD are equal in length. This means that ABD must …
