Firstly , we can draw diagram
we can see that
adjacent = 850
opposite =250
so, we can use tan formula

A system of equations is:B ) x + y = 375 x = 2 y - 60 We will solve this system: 2 y - 60 + y = 375 3 y = 435 y = 435 : 3 y = 145 x = 375 - 145 x = 230Allan`s score was 230 and Dave`s score was 145.
