The answer to your question is below

Step-by-step explanation:

23.- According to the picture I can conclude that is an isosceles triangle,

then,   45° =  2   so

          45° = x + 60

          x = 45 - 60

         x = -15

24.- This is also an isosceles triangle, then,  2 = 74

                     3x - 4 = 32                   2x 74   = 148

                     3x = 32 + 4                  180 - 148 = 32 = 3x - 4

                      3x = 36

                   x = 12

25.-  This is an equilateral triangle, then,

                 60 = 7x - 10

                60 + 10 = 7x

                70 = 7x

                x = 70/7

                x = 10
