sin = opposite/hypotenuse

sin 40° = 12/x

Cross multiply.

0.64278760968x = 12

Divide both sides by sin 40°.

x = 18.7 (rounded to nearest tenth).

Answer: 18.7

Step-by-step explanation:

From the diagram opposite side = 12

hypotenuse side=X

θ= 40⁰

Sinθ= opposite/hypotenus

Sin40= 12/X

Cross multiply

Xsin40° = 12

Divide bothside by sin40°

X = 12/sin40°

x= 12/0.64279

X= 18.6686

X=18.7

professor190 [17]

Answer:

\large\boxed{k=\dfrac{2m+3}{7-r}\ \text{for}\ r\neq7}

Step-by-step explanation:

7k+2m=kr+4m+3\qquad\text{subtract}\ 2m\ \text{from both sides}\\\\7k+2m-2m=kr+4m-2m+3\\\\7k=kr+2m+3\qquad\text{subtract}\ kr\ \text{from both sides}\\\\7k-kr=kr-kr+2m+3\\\\7k-kr=2m+3\qquad\text{distribute}\\\\k(7-r)=2m+3\qquad\text{divide both sides by}\ (7-r)\neq0\\\\k=\dfrac{2m+3}{7-r}
