Find a set of parametric equations for the line of intersection of the planes x-3y+6z=4 5x+y-z=4

Inessa05 [86]

Answer:

Step-by-step explanation:

Two equations of planes are given.

We have to find the equation of the line which is formed by intersection of these two planes in parametric form

$x-3y+6z=4 \\5x+y-z=4$

Let us eliminate one variable

Multiply I equation by 5 and subtract II from 5 * I

$5x-15y+30z=20 \\5x+y-z=4$

$-16y+31z=16 \\$

$16y+16 = 31z$

Or $y+1 =\frac{31z}{16}$

Consider II equation

5x+y-z=4

$5x+\frac{31z}{16}-1 -z=4\\5x+\frac{15z}{16}=5\\x=\frac{3z-16}{16}$

Let z=z

x = \frac{3z-16}{16} and y = \frac{31z}{16}-1

An isosceles triangle has an angle that measures 26°. Which other angles could be in that

snow_tiger [21]

Answer:

26° 26° 128°

77° 77° 26°

Step-by-step explanation:

So we have two scenarios here.

One of them is if the base angles are 26°.

If that's true, the other angle is 128°

The other scenario is the opposite.

This means the base angles are 77°
