Transcribed Image Text:Use the triangle below to answer the questions. Assume x and y are positive.
0
(a) Express x as a function of y.
Ox= 100 - y²
O x = 10 - y
Ox= √² + 100
Ox= √²-100
O x = y + 10
(b) Express 8 as a function of y.
O 8 = tan 1-1(10)
1-¹ (1-0)
O 8= sin 1
5-1¹ (16)
10
08= cos
10
in-¹(¹0)
O sin 1
O 8= cos
= cos-1/10
