The given functions are:
and
We want to find
.
Recall that:

We substitute the functions to get:

We now write in standard form to obtain:

Step-by-step explanation:
angle on a straight line is 180, thus , the angle on the line inside the triangle is
180 - 96 = 84
and since the sum of the angles in a triangle is 180 ,
the angle 1 is ..
180 - 29 - 84 = 67 degrees ,
therefore the answer is D
