Answer:
Choice A
Step-by-step explanation:
This is because you just need to find Angle AGE, and you have found x. You find this by adding up 51 plus 90, and subtracting it from 180, to get it, because those three top angles are supplementary.
We are given with the expressions above and translate them into
tan x = a / 4 and
cos x = 4 = b
According to the trigonometric identities, tan x = sin x/ cos x, hence
sinx = tan x * cos x = (a/4)*4 or equal to a. The answer is C. 4a.
23+15=38
so basically that is super easy to kno, i ddi it for you because i need cins asap
Answer:
D
Step-by-step explanation:
Quadratic has a general form of:

The quadratic given here is:

Matching it with the general form, we can see that:
a = 1 [coefficient of x^2]
b = 3
c = 1
Now, if we look at the formula for axis of symmetry, we can easily solve this out. The axis of symmetry is given by:
Axis of Symmetry is 
We know a = 1 and b = 3, so we have:

Hence,
D is the correct answer.
13/15: exact form
0.86 repeating: decimal form
