Question

Help:(, i’m not sure how to do this

Answer 1

Answer:

i think you have to multiply the sides..

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

1) PQ² + PR² = QR²

PQ² + 14² = 50²

PQ² + 196 = 2500

           PQ² = 2500 - 196 = 2304

            PQ = √2304

PQ = 48

Sin Q = $\frac{opposite side}{hypotenuse}=\frac{14}{50}$

$Cos Q = \frac{adjacent side}{hypotenuse}=\frac{48}{50}\\\\Tan Q = \frac{oppsite}{adjacent}=\frac{14}{48}\\\\\\\Sin R = \frac{48}{50}\\\\Cos R = \frac{14}{50}\\\\Tan R = \frac{48}{14}$

2) tan 48 = $\frac{x}{17}$

x = 17 * tan 48  = 17 * 1.1106 = 18.8802

x = 18.8802
