Given : mn is an angle bisector of (angle)jmk prove : m(angle)jmn=1/2m(angle)jmk (i need all the reasons)

The complete proof with reasons is explained in step-by-step explaination.

Step-by-step explanation:

Given an angle ∠JMK=m and also MN is the line which bisects the angle ∠JMK that means MN is the line which equally divides the angle ∠JMK.

∠JMK=m

∠JMK = ∠JMN + ∠NMK

It is given that the two angles equally divides by line MN i.e ∠JMN=∠NMK.

⇒  ∠JMK=∠JMN+∠JMN

⇒      m = 2∠JMN        

By mulitiplication property of equality

⇒       ∠JMN=  

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
