If a unit vector is represented by `0.5hati + 0.8hatj + chatk` the value of c is

If a unit vector is represented by 0.5 hati + 0.8 hatj + c hatk ,the value of c is

If a unit vector represented by 0.5hati-0.8hatj+chatk , then the value of 'c' is :

If a unit vector represented by 0.5hati-0.8hatj+chatk , then the value of 'c' is :

If a unit vector is represented by 0.4 hati+0.7 hatj + chatk then the value of c is

If a unit vector is represented by 0.4 hati+0.7 hatj + chatk then the value of c is

If a unit vector represented by 0.8hati-0.8hatj+chatk , then the value of 'c' is :

If a unit vector is represented by 0.5 hat(i) + 0.8 hat(j) + c hat(k) , then the value of c is

If a unit vector is represented by 0.5 hat(i) + 0.8 hat(j) + c hat(k) , then the value of c is

A unit vector is represented by ahati + bhatj + chatk . If the values of a and b are 0.6 and 0.8 respectively, find the value of c.
