In the diagram at below, m m I need help understanding this, please help!!!
tensa zangetsu [6.8K]

Answer:

m<BAC= 110 degrees

Step-by-step explanation:

Since the outside angle m<BCD is 130 degrees the inside angle m<BCA would be 50 degrees. At this point you should know that inside angles of a triangle add up to 180 degrees so add the two angles that you know then subtract from 180 degrees. 50+20= 70 degrees and 180-70= 110 degrees.

In this problem, the price of the products bought is given by:

What fraction is greater than 1/2 but less than 3/4
aliya0001 [1]
1/2 = 50%

3/4 = 75%

So something in between that could be 2/3 (which equals 66.67% )

A few others could be: 3/5 ( equals to 60% ) , 7/10 ( equals 70%) 

Hope that helps :)
