Name the major arc and find its measure
marin [14]
The largest arch for this case is the ADB arch.
 To know the size of the major arc, the first thing you should keep in mind is that the entire circumference measures 360 degrees.
 We then have the following equation:
 ADB + 50 = 360
 From here, we clear the value of ADB.
 We have then:
 ADB = 360 - 50
 ADB = 310 degrees.
 Answer:
 
The measure of the major arc is:
 
ADB = 310 degrees.

A prism with a square base has a height of 15cm and a volume of 735cm3. Find the length of each edge of the base.
denis-greek [22]

Answer:

The length of each edge of the base is 7cm.

Step-by-step explanation:

The volume of a prism with square base is given by:

V = l^{2}h

In which l is the length of each edge of the base and h is the height.

A prism with a square base has a height of 15cm and a volume of 735cm3.

This means that V = 735, h = 15

So

V = l^{2}h

735 = 15l^{2}

l^{2} = \frac{735}{15}

l^{2} = 49

l = \pm \sqrt{49}

Length is a positive measure. So

l = 7

Volume in cm³, so the length of each edge is in cm.

The length of each edge of the base is 7cm.
