Which of the following is true about a kite?a.All angles are rightb.The diagonals have the same lengthc.All four sides are equal
1 answer:
In a kite, there is always an angle that is not right, otherwise, it would have a rectangular shape.
The diagonals are not of the same length because that would mean it would have a rectangular shape as well.
The sides are not equal, because that would mean it would have a rhomboid shape, to which a square belongs to.
The top edges are congruent with each other, as well as the bottom ones. This is because you can turn one into the other by reflecting them using an isometry, so D is true.

Answer: 140
Step-by-step explanation:
The area for a trapeziod is A = (b1+b2)h
We have almost everything we just need the total length of the top base, since it gives us the outer lengths we can find that by simply doing 4+6+15 which turns out to be 25
Now we can plug in our values:
A = (25 + 15) x 7 = 140
