Total for all triangles=180

Step-by-step explanation:

In all the problems, you have to solve for y. This can be done because the three angles are supplementary For example, in the first diagram, you have:

3y+2y+y=180

6y=180

y=30

It's fairly easy to solve from there. Just more multiplying and subtracting.

True [87]

Answer:

$\frac{9x}{y^3}$

Step-by-step explanation:

$\frac{\left(3x^2y^4\right)^3}{3x^5y^{15}}$

$(3x^2y^4)^3 : 3^3x^6y^1^2$

= $\frac{3^3x^6y^{12}}{3x^5y^{15}}$

$\frac{3^{3} }{2} = 3^{2}$

= $\frac{3^2x^6y^{12}}{x^5y^{15}}$

= $\frac{x^{6} }{x^{5} } : x$

= $\frac{3^2xy^{12}}{y^{15}}$

= $\frac{y^{12} }{y^{15} } : \frac{1}{3{y} }$

= $\frac{3^2x}{y^3}$

$3^2=9$

= $\frac{9x}{y^3}$
