Answer:
Area = 33 inches squared
Step-by-step explanation:
The formula for the area of a kite is:
Area = ½ × (d)1 × (d)2
To find the first diagonal (d1):
d1 = 7 in + 4 in = 11 in
To find the second diagonal (d2):
The triangles on the right of the kite must be 3 4 5 triangle since it is a right triangle with a hypotenuse of 5 and a side of 4, we know half of a diagonal would be 3 inches.
d2 = 3 in + 3 in = 6 in
Now we can plug the diagonals into the area formula.
Area = ½ × 11 × 6 = 33 inches squared
Answer: 17 and 25
Step-by-step explanation:
Let X and Y be the two numbers.
---------------
X + Y = 42 [sum of two numbers is 42]
X - Y = 8 [their difference is 8]
-------------------
Rearrange the last equation to
X = 8 + Y
Now enter that into the 1st equation:
X + Y = 42
(8+Y) + Y = 42
2Y = 34
<u>Y = 17</u>
Since X - Y = 8,
X = 8 + 17
<u>X = 25</u>
===
X + Y = ?
17 + 25 = 42 <em>Checks</em>
X - Y = ?
25 - 17 = 8 <em>Checks</em>
