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.
Possible outcomes: 5040
Possible to begin with a 0: 504
Theoretical probability: 0.1
These are the correct answers
Answer
its the third one.
Step-by-step explanation:
this depends. you can measure angles in real life with a protractor or just use your eye. let us start with the protractor. place the midpoint of a protractor on the vertex of the angle and make sure it lines up to 0. on the other side read the degrees (make sure everything aligns). without a protractor you can use the Sine Formula and measure the lines.
