Question

PQR is a tringle, right angle at P.if PQ =10cm and PR =24cm find​

Answer 1

Answer:

26cm

Step-by-step explanation:

Let the RQ be x cm,

In right angle triangle PQR,

h^2\ =\ b^2+p^2h  

2

 = b  

2

+p  

2

 

QR^2\ =\ PQ^2\ +PR^2\QR  

2

 = PQ  

2

 +PR  

2

 

x^2=\ \left(10\right)^2+\left(24\right)^2x  

2

= (10)  

2

+(24)  

2

 

x^2\ =\ 100\ +576x  

2

 = 100 +576

x\ =\ \sqrt{100+576}x =  

100+576

​  

 

x\ =\ \sqrt{676}x =  

676

​  

 

x = 26 cm

Thus, the length of QR is 26cm.
