Step-by-step explanation:
Hypotenuse = 22
Since the two angles other than the 90° are both
45° , it means that the two legs of the right triangle are of equal length.
So, (x)²+ (x)² = 22²
2x² = 22²
x² = 484/2
x² = 242
x = √242
x = 15.55
x ≈ 15

Step-by-step explanation:
1. L= i + 2j +k; P = -3i + j + k, line lies on one another at k
2. L =i + 2j + k and P = 6i -3j + k, the lines lie on one another at k
3. P = ai + bj and -2bi +2aj + (a+b) k
