Question

the hypotunce of of aright angle is 26cm long

Answer 1

Answer:

As per Pythagoras theorem, we know,

Base²+ Height²= Hypotenuse²

Let base be one of the given sides.

Height is to be found then,

10²+x²= 26²

x² = 26²-10²

x²= 676-100

x²= 576 cm

Therefore, the other side ( x) is 24 cm.

Hope you understood

8.i) is right angled triangle.

9. As per rule, two interior angles sum make an exterior angle.

70°(given) + x= 110°

x= 40°

Dear, you can use angle sum property if you wish. But that might be too lengthy.. hence this method I used.

10. 34 cm

Hope your doubts were cleared.
