Answer:
The correct answer is option 3.
Step-by-step explanation:
Given : ΔPQR, QM is altitude of the triangle
PM = 8
MR = 18
To find = QM
Solution :
PR = 8 + 18 = 26
Let, PQ = x , QR = y, QM = z
Applying Pythagoras Theorem in ΔPQR

..[1]
Applying Pythagoras Theorem in ΔPQM

..[2]
Applying Pythagoras Theorem in ΔQMR

..[3]
Putting values of
and
from [2] and [3 in [1].




z = ±12
z = 12 = QM ( ignoring negative value)
The length of QM is 12.
Answer:
6, 9, 12
Step-by-step explanation:
Let s be the shortest side. Using the information you're given, you can create an equation. 27= s + s+3 + 2s. Now just solve the equation. Subtract 3 from both sides. 24=4s. Divide by 4 on both sides. 6=s. So the shortest side is 6 feet long, so we add 3 to that for the one that is neither the shortest or the longest. That side is 9 feet long. We double s to get 12, which is the longest side.
Answer:
51
Step-by-step explanation:
102 divided by 2 is 51
Take the letter out and replace it with the number that has the exact letter like x-10.
v = w - 20
move -20 to the other side
sign changes from -20 to +20
to get w by itself
v+20= w-20+20
Answer:
w= v+20 or w= 20+v
