Answer:
A
Step-by-step explanation:
the sum of the two angles is 90 degrees
x + 52 = 90
x = 38 degrees
Answer:

Step-by-step explanation:
We are asked to find the tangent line approximation for
near
.
We will use linear approximation formula for a tangent line
of a function
at
to solve our given problem.

Let us find value of function at
as:

Now, we will find derivative of given function as:




Let us find derivative at 

Upon substituting our given values in linear approximation formula, we will get:


Therefore, our required tangent line for approximation would be
.
Answer:
C
Step-by-step explanation:
The secant- secant angle SPR is half the difference of the intercepted arcs, that is
55° =
(RS - QT ) ← multiply both sides by 2
110° = RS - QT = RS - 50° ( add 50° to both sides )
160° = RS → C
