Answer:
B
Step-by-step explanation:
Angle 4 × Angle 3 = 90
Complementary angles
11x + 4x = 90
15x = 90
x = 6
Angle 3 = 4x = 4(6) = 24°

The first term is, <span> <span>n2</span> </span> its coefficient is <span> 1 </span>.
The middle term is, <span> +2n </span> its coefficient is <span> 2 </span>.
The last term, "the constant", is <span> +4 </span>
Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 1</span> • 4 = 4</span>

Answer:
C and D
Step-by-step explanation:
Its that simple
Answer:
...
Step-by-step explanation:
remeber that for every angle they give you, you need to subtract 90 from it to get the answer.
Answer: Undefined
Step-by-step explanation:
(slope = m)
(3 divided by 0 is undefined, so the slope is undefined)
