The image you uploaded contains several geometry problems, which appear to involve right triangles. Let's break down the problems:

1. Problem 10: You have a right triangle with one angle of 64° and a side of length 42. You're asked to find the length of side $x$. This can be solved using trigonometric ratios such as sine, cosine, or tangent, depending on the missing information.

2. Problem 11: Here, you have a right triangle where the angle is 70° and the side opposite to it has a length of 13. You need to find the length of side $y$. Again, trigonometric functions will be used.

3. Problem 12: You are asked to find $DC$ in triangle $ABC$, where the right angle is at $D$. Side $AB$ has a length of 20, and angles are given as 54° and 28°. You can apply the Law of Sines or the Law of Cosines to solve this.

4. Problem 14: A 30-foot tall telephone pole is connected to the ground with a wire that forms a 48° angle with the pole. You're asked to find the length of the wire. This is another trigonometry problem, which can be solved using the sine or cosine rule.

Would you like to focus on any specific problem, or would you like me to solve them step by step for you?
