Answer:
No, it is not 
Step-by-step explanation:
Here, we want to check if the lenghts given is that of a right angle triangle 
For a right angle triangle, the square of the hypotenuse is equal to the sum of the squares of the two other sides 
The hypotenuse represents the longest side 
So 27^2 = 14^2 + 23^2
The difference between these is 4, and as such the triangle is not a right angled 
 
        
             
        
        
        
The length of PQ is 19.66 units
Step-by-step explanation:
The given is:
1. PK = KQ = 12 
2. m∠P = 35º
We need to find the length pf PQ
∵ PK = KQ
∴ m∠P = m∠Q
∵ m∠P = 35°
∴ m∠Q = 35°
The sum of measures of the angles of a triangle is 180°
∴ m∠P + m∠Q + m∠K = 180°
∴ 35 + 35 + m∠K = 180
∴ 70 + m∠K = 180
- Subtract 70 from both sides
∴ m∠K = 110°
Let us use cosine rule to find the length of PQ
∵ PQ = 
∵ PK = 12 , KQ = 12 , m∠K = 110°
- Substitute these values in the rule
∴ PQ = 
∴ PQ = 19.66
The length of PQ is 19.66 units
