Consider the multiplication 999 xx abc = def132 in decimal notation, where a, b, c, d, e and f are digits. What are the values of a, b, c, d, e and f respectively ?

Calculate the area of the pentagon A B C D E , where A B=A E and with dimensions as shown in Fig.36.

In an isosceles triangle ABC with A B" "=" "A C , D and E are points on BC such that B E" "=" "C D (see Fig. 7.29). Show that A D""= "A E

In Figure, A B_|_B E\ a n d\ F E\ _|_B Edot If B C=D E\ a n d\ A B=E F , then A B D is congruent to: E F C (b) E C F (c) C E F (d) F E C
