1. Which description does NOT guarantee that a t ɾąքҽ zoid is isosceles?
a) both pairs of base angles congruent
b) congruent bases
c) congruent diagonals
2. One side of a kite is 8 cm less than four times the length of another side. The perimeter of the kite is 78 cm. Find the lengths of the sides of the kite.
a) 23.5 cm and 86 cm
b) 23.5 cm
c) 9.4 cm and 29.6 c
10 points for best answer that actually is correct
1) b) congruent bases
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
y= 4(9.4)-8 = 29.6
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.
