Answer:
Yes ,because of SAS similarity theorem
Step-by-step explanation:
In ΔYOM , ΔTON
∠YOM = ∠TON

SAS similarity theorem
Its the last answer (-1+radical 3)/2

Answer:
Step-by-step explanation:
you have right triangle & isosceles
so is 45-90-45
PR^2=PQ^2+QR^2
c^2=a^2+b^2, where c is the hypotenuse, and a=b
(3
)^2=2a^2
18=2a^2
9=a^2
a=3, b=3, both legs are equal to 3
