Answer:
Okay so what you are looking at is a triangle with a cross section. That is line segment PQ.You ae asked to find the length of PN. What you are given is the height(s) of NQ (5 units), QM (2 units) and PL (3 units). You can make an educated guess that line NP equals 4 units.

Answer:
Mikhail is 5 years old
Step-by-step explanation:
Represent each member with a variable.
X= Gabrille
Y=Mikhail
X+Y=20 (sum of their ages is 20)
X=3y (Gabrille is 3 times Mikhails age)
Substitute 3Y into the first equation (simultaneous equation)
. 3y+y=20
. 4y=20 (divide both sides by 4)
y=5
To check your answer.
X+5=20
X=20-5
X=15
15 is 5 times 3.
