Answer:
The two considered triangles are similar by the AA rule of similarity.
Step-by-step explanation:
It is given that two triangles that are JKL and MNP are considered in which ∠K= ∠N,∠L= ∠P, JK=6, and MN=18.
Now, from ΔJKL and ΔMNP, we have
∠K= ∠N (Given in the question)
∠L= ∠P(Given in the question)
Thus, by AA rule of similarity,
ΔJKL is similar to ΔMNP.
Thus, the two considered triangles are similar by the AA rule of similarity.
Answer:
Required equation of tangent plane is .
Step-by-step explanation:
Given surface function is,
To find tangent plane at the point (5,-1,1).
We know equation of tangent plane at the point $(x_0,y_0,z_0)[/tex] is,
So that,
Substitute all these values in (1) we get,
Which is the required euation of tangent plane.
