If llm and m<6 = 4x - 15 and m<7 = x + 30, then m<6=

Step-by-step explanation:

There are only 2 angle values  that <1 to <8 can be. The two values add up to 180

In this case <6 and <7 are equal.

<6 = 4x - 15

<7 = x + 30

4x - 15 = x + 30             Subtract x from both sides

4x-x - 15 = 30                Add 15 to both sides

3x = 30 + 15

3x = 45                         Divide by 3

x = 45 / 3                          

x = 15

<6 = 4x - 15

<6 = 4*15 - 15

<6 = 60 - 15

<6 = 45

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

thus, the first answer choice, y = sec x, is the correct one
