All euros have a national image on the "heads" side and a common design on the "tails" side. spinning a coin, unlike tossing it, may not give heads and tails with equal probabilities. polish students spun the belgian euro 250 times, with its portly king, albert, displayed on the heads side. the result was 150 heads. how strong is the evidence against equal proportions of heads and tails

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

idk man good luck man

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
