We're provided : In right angled triangle PQR , The length of of PR & length of PQ are 10 cm & 6 cm respectively & we're asked to find out the length of OR.
You need to know : The longest side, which is the opposite side of right angle is the hypotenuse ( h ) . When the reference angle is not given , You can assume the remaining sides either perpendicular ( p ) or base ( b ) .
Here , Hypotenuse ( h ) = 10 cm , Base ( b ) = ? & Perpendicular ( P ) = 6 cm
Before solving, You will have to know : The square of the hypotenuse of a right - angled triangle is equal to the sum of square of the remaining two sides.
- Plug the known values and then simplify !
Hence , The length of QR is 8cm .

Jose is false because the sun which makes it a day only shines none side of the earth while the moon is on the other side so on the other half of the hemisphere the days would be getting shorter while the days get longer on the other half of the hemisphere.
