$\bf a^3b^{-2}c^{-1}d\implies \cfrac{a^3d}{b^2c}\qquad \begin{cases} a=2\\ b=4\\ c=10\\ d=15 \end{cases}\implies \cfrac{2^3\cdot 15}{4^2\cdot 10}\implies \cfrac{120}{160}\implies \cfrac{3}{4}$

The answer is C. 2x-70 and x+30 are congruent (equal in size) so 2x-70=x+30
then you find that x=100. So we solve 2(100)-70=130. We then solve for Y with 5y+130=180 Linear angles Paris always add to 180. We come out with Y=10
