Answer:
This is a right triangle, so we know that:
h² = b' · c'
which is this case can be specificly written as:
BD² = AD · CD
BD² = 7 · 3 = 21
BD = √21
Now that we can also notice that ΔADB is also a right triangle, therefore we can apply the pythagorean theorem:
AD² + BD² = AB²
7² + (√21)² = x²
x² = 49 + 21 = 70
x = √70
The answer is c because if you add 2 sides and the two sides are greater than the third than the triangle is possible
Short Answer RP = 8 meters.
Remark
A kite's diagonals bisect each other. (1/2) QS = QP.
Another fact about a kite is that the diagonals meet at right angles.
ΔQPR is a right triangle.
Step One
Find QP
QP = 1/2 QS
QS = 12 Given
QP = 1/2 12
QP = 6
Step Two
Find RP
Use the Pythagorean Theorem To solve for RP
<em>Givens</em>
QP = 6 From Step 1
QR = 10 Given
QP = ??
We are dealing with a right angle triangle.
RP^2 + QP^2 = QR^2
RP^2 + 6^2 = 10^2
RP^2 + 36 = 100 Subtract 36 from both sides.
RP^2 = 100 - 36
RP^2 = 64 Take the square root of both sides.
sqrt(RP^2) =sqrt(64)
RP = 8 <<<<<<<< Answer
