If n is the number of books, lets say 1 book is "x", then

n=1    then x=65

n=2 then x=65/2

n=3 then x=65/3

Find the values of X and Y in an isosceles triangle where one angle is 47°
vladimir1956 [14]

Answer:

X and Y = 66.5°.

ruslelena [56]

Answer:

<h3>           m∠BAC = 80° </h3>

Step-by-step explanation:

m∠BCD = 145°  ⇒  m∠BCA = 180° - 145° = 35°

From ΔABC:

                    m∠ABC + m∠BCA + m∠BAC = 180°

                         65° +  35° + m∠BAC = 180°

                                  m∠BAC = 180° -  100°

                                   m∠BAC = 80°
