Write the equation of the line that passes through (4,3) and (4,0)
jolli1 [7]

Answer:

x = 4

Step-by-step explanation:

Note the x- coordinate of the 2 points are equal.

This indicates the line is vertical with equation

x = c

where c is the value of the x- coordinates the line passes through, that is 4

Thus the equation of the line is x = 4

Which equation shows a correct relation for triangle RSQ?
son4ous [18]

Answer:

sinQ=cosR

Step-by-step explanation:

First we need to find out the measure of ∠R.

The sum of all the angles in a triangle add up to 180. Therefore:

∠Q+∠R+∠S=180

66+∠R+90=180

∠R=180-156

∠R=24°

Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.

sinQ=cosR

sin66=cos24

0.9135454576=0.9135454576

So the second equation is the correct relation.
