First factor out the 2:
x^2 - y^2 = 36
x^2 - y^2 can be factored into (x+y)(y-y) so:
(x + y)(x - y) = 36
plug in your value:
18 (x-y) = 36 and you should be able to take it from there
Answer:
your non rounded yo answer is 107.1
Answer:
Step-by-step explanation:
The sides of a triangle are 6cm, 6cm, and 4cm.
According to triangle inequality, the sum of the length of any two sides of a triangle must be greater than the length of the third side.
So,
6+6=12>4
6+4=10>6
4+6=10>6
Therefore, the theorem of triangle inequality is satisfied for all three possible cases. This implies that only one triangle can be constructed with sides measuring 6cm, 6cm, and 4cm.
Answer:

Step-by-step explanation:
Answer:

Step-by-step explanation:
Evaluate cos(tan^-1 0)

We know that tan(0)=0
tan (0 degree)=0

Replace it in our problem


At 0 degree the cos value is 1
So co(0)=1
