Answer:

Step-by-step explanation:
We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is
.
Because all the angles of a triangle sum to
, we have that
.
We combine like terms on the left side to get
.
We subtract
on both sides to get
.
So,
and we're done!
Answer:
1/12
Step-by-step explanation:
The probability of rolling a 4 is 1/6.
The probability of flipping heads is 1/2.
The probability of both is 1/6 × 1/2 = 1/12
