Task 1 - Bridge over The River Gauss

A new bridge was built to the north of the park over the Gauss River.  The bridge is for pedestrians and cyclists only. The bridge is called a cable stayed bridge and it is similar to the one below:

Each section of the bridge in Mathville has a central tower that is 30 m high.

The support cables extend from the top of the tower to different places alongside the bridge surface. 
1.	Determine the length of the three support cables shown on the right side of the tower. Round answers to 1 decimal.
2.	Determine the angle that each support cable shown on the right side makes with the bridge surface. Round to the nearest degree.
