There can only be one reason for that . . . making
something tough out of something easy.

-19 = x - 7

How could you get 'x' all by itself on one side,
and everything else on the other side ?

What if you add 7 to each side ?

Then you have  -12 = x  . To your amazement, that's the solution !

Troyanec [42]

Answer:

$\large\boxed{m\angle R\approx76^o}$

Step-by-step explanation:

$\dfrac{\sin R}{SQ}=\dfrac{\sin S}{RQ}\\\\\text{We have:}\\\\SQ=32,\ RQ=26,\ S=52^o\to\sin52^o\approx0.788\\\\\text{Substitute:}\\\\\dfrac{\sin R}{32}=\dfrac{0.788}{26}\qquad\text{multiply both sides by 32}\\\\\sin R\approx0.97\to R=\arcsin(0.97)\\\\R\approx76^o$
