Question

calcule x e y em grau sabendo que abc = rst ​

Answer 1

$\large\boxed{\begin{array}{l}\sf \triangle ABC\cong \triangle RST\\\sf\dotsi 3y=45^\circ\\\sf\dotsi y=\dfrac{45^\circ}{3}\\\\\dotsi\sf y=15^\circ\\\sf\dotsi 7x+2y=58^\circ\\\sf\dotsi 7x+2\cdot15^\circ=58^\circ\\\sf\dotsi 7x+30^\circ=58^\circ\\\sf\dotsi 7x=58^\circ-30^\circ\\\sf\dotsi7x=28^\circ\\\sf\dotsi x=\dfrac{28^\circ}{7}\\\\\sf\dotsi x=4^\circ \\\huge\boxed{\boxed{\boxed{\boxed{\sf\red{\dagger}~\blue{espero~ter\,ajudado}}}}}\end{array}}$
