Answer:

Explanation:

1) PQ² + PR² = QR²

PQ² + 14² = 50²

PQ² + 196 = 2500

PQ² = 2500 - 196 = 2304

PQ = √2304

PQ = 48

Sin Q =
(opposite side)/(hypotenuse)=(14)/(50)\\


Cos Q = (adjacent side)/(hypotenuse)=(48)/(50)\\\\Tan Q = (oppsite)/(adjacent)=(14)/(48)\\\\\\\Sin R = (48)/(50)\\\\Cos R = (14)/(50)\\\\Tan R = (48)/(14)\\\\

2) tan 48 =
(x)/(17)

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

x = 18.8802
