If you add the two ratios together you get 10. Which means that the £50 is made up of 10 pieces. To get Doras amount you have to divide 50 by 10 which is five, and then times the number by how many pieces Dora has, which would be 5x3=15
The first two angles are both complementary angles since they add up to 90* I can’t see the last angle too well I think it’s a supplementary angle since it has a straight line meaning it should equal 180*
