  • 1) b) congruent bases

    2)

    Let x and y be the sides.

    y = 4x-8

    Perimeter = x+x+y+y

    Perimeter = x+x + (4x-8)+(4x-8) = 10x-16 = 78

    10x=94

    x=9.4

    y= 4(9.4)-8 = 29.6

    (c)

  • it particularly isn’t the corner for cheating on homework. I advise you spend a while drawing the right triangles. For question 4 you are able to revise the formulae for deriving section and circumference from the radius. question 5 is an workout in logic. try drawing triangles for that as properly.

  • that isn’t the nook for cheating on homework. I advise you spend it gradual drawing the desirable triangles. For question 4 you are able to desire to revise the formulae for deriving area and circumference from the radius. question 5 is an exercising in good judgment. attempt drawing triangles for that as nicely.
