Question

5,12 are two perpendicular sides of a right angle find the third angle​

Answer 1

Answer:

here,

a = 5

b= 12

to find c = ??

according to Pythagoras theorem,

c² + a² + b²

=> c² = 5² + 12²

=> c² = 25 + 144

=> c² = 169

=> c = √169

=> c = 13

so,

third side is 13 unit.

Answer 2

Step-by-step explanation:

According to the question,

In the right angled triangle ,

the third side = √12square +5square

=√144+25=√169=13

sum of two angles =90
