Answer:
170°
Step-by-step explanation:
We can already see that measure ∠AD is equal to 85
A square has two halves, so this square will be added.
We will have to add 85 + 85 which equals 170°
Answer:
x = -2
Step-by-step explanation:
The tangent line has length "x + 8"
The secant line has length "x + 6 + 5", where
5 is the inner part
x + 6 is the outer part
Now,
the secant-tangent theorem tells us that square of the tangent line is equal to the outer segment of secant line multiplied by length of whole secant line.
So, we can say:

We can solve for x shown below:

The value of x is -2
Answer: 1.032
1.29/1.25 = 1.032
