Eddi Din [679]

Answer:

$\sf y=\dfrac{5}{3}x+4$

Step-by-step explanation:

<u>Given:</u>

<u /> $\textsf{slope of $\dfrac{5}{3}$, and a y-intercept of $4$}$

⇒ Slope-Intercept Form: y = mx + b

<u>where:</u>

m is the slope
b is the y-intercept (when x = 0)

Substitute the given values:

$\sf\\ \implies y=mx+b\\\\\implies y=\dfrac{5}{3}x+4$

You need the Law of Sines for this. In our case we have the measure of angle B and side b, we have the measure of angle A and are looking for side a, or x. Setting up the Law using our info, we have $\frac{x}{sin(42)} = \frac{9}{sin(29)}$ . We will solve for x by multiplying both sides by sin(42): $x= \frac{9sin(42)}{sin(29)}$ , first choice above.
