We have the following givens:
a=25 
b=16
c=9
We can make use of the Laws of Cosines in solving the angle A such as:
cos A = (b²+c²-a²)/2bc
cos A =((16)²+9²-(25)²)/1*16*9
A=180°

tan (A/2)=tan(180/2)

A baker made 9 cupcakes, each a different type. Four people want to share them equally. How many cupcakes will each person get?
Leno4ka [110]

Answer: 2 1/4

Step-by-step explanation:

From the question, we are informed that a baker made 9 cupcakes which are to be shared equally by four people.

To get the number of cupcakes that each person gets, we divide the total number of cupcakes by the total number of people. This would be:

= 9 ÷ 4

= 2 1/4 cupcakes

Therefore, each person gets 2 1/4 cupcakes.
