Answer 1

HERE IS THE PROBLEM

Answer 2

Answer is 24 cm.

Answer 3

From the diagram, we see a tangent line. Thus, it forms a right angle. From this, we know that it is a right triangle and we can use the Pythagorean Theorem. a squared + b squared equals c squared.

Answer 4

x) Tangent lines are perpendicular to the circle. THen use triangle sum theorem to solve for x by doubling the remaining angle. 180 - 90 - 16.3 = 73.7 x 2 = 147.4º
y) 360 - x = y
360 - 147.7 = 212.3
z) Pythagorean Theorem.
7^2 + z^2 = 25^2
49 + z^2 = 625
z^2 = 576
z = 24
