Question

If x = 10, y = 5, and z = 11, what is the cosine ratio for g°?

Answer 1

Answer:

X+ 7 = 21 - 7 - 7x = 14

Step-by-step explanation:

replace x values and y values with the answer choices.

$y=(1)^2- 1 = 0$

$y= 2(1)-2=0$

since the coordinate pair $(1,0)$ it is safe to assume that d will be the correct answer.

use the graph to confirm that the solution is (1,0)

the blue line intersects at (1,0), so the solution for the system of equations is (1,0)

Answer 2

Answer:5/11 (A)

Step-by-step explanation: In the diagram y is adjacent to <B and the hypotenuse is obviously z. Remember that cosine = adjacent/hypotenuse, therefore the answer is 5/11
