Step-by-step explanation:
WX is parallel to YZ and WZ is also parallel to XY
? can be any number except for 3 or -2 as it is already used in (3,4), (-2,-5)
Step-by-step explanation:
y=X -3/X
y=X/1 -3/x
y= 2x -3/x
y*X= 2x-3
y*X/2 = x-3
Answer:
The first one sounds suprising but what is the action?
Using pythagorean identities,tan(sin^-1(-5/13))= tan(arcsin(-5/13))
Let A = arcsin(-5/13) = -arcsin(5/13)
Thus, sin A = -5/13 and cos A = sqrt(1 - (5/13)^2) = 12/13.= tan(A)= sin(A) / cos(A)= -5/13 / (12/13)= -5/12
