Write each of the following as a function of theta.
1.) sin(pi/4 - theta) 2.) tan(theta+30°)

Step-by-step explanation:

Let x represent theta.

Using the angle addition trig formula,

Multiply one side at a time

Replace theta with x , the answer is

2. Convert 30 degrees into radian

Using tangent formula,

Tan if pi/6 is sqr root of 3/3

Since my phone about to die if you later simplify that,

you'll get

Replace theta with X.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal
