Answer:

Two negatives

Step-by-step explanation:

I'm assuming by 'factors of c' you mean factors of the last term. For the entire trinomial, we know that there are two negative signs. To be able to get a negative 11x and then a positive 10, we would need two negatives, since two negatives equal a positive. Hope that helps!

A right triangle in which one acute angle is a reference angle for a 115 degree angle in standard position intersects the unit c

Ratling [72]

Answer:

$\cos (115\degree)=-0.423$

Step-by-step explanation:

The parametric equations of a circle is

$x=r\cos \theta$ and $y=r\sin \theta$

The radius of the unit circle is 1 unit.

This implies that any point on the unit circle is represented by:

$x=\cos \theta$ and $y=\sin \theta$

where $\theta$ is the angle in standard position,

From the question, the given angle in standard position is $115\degree$ .

This angle intersects the unit circle at $x=-0.423$

But $x=\cos \theta$

We substitute $\theta=115\degree$ and $x=-0.423$

This implies that: $\cos (115\degree)=-0.423$

What is the value of x?

vekshin1

Answer:

x = 58

Step-by-step explanation:

The secant- tangent angle 51° is calculated as half the difference of the intercepted arcs, that is

$\frac{1}{2}$ (160 - x) = 51 ← multiply both sides by 2 to clear the fraction

160 - x = 102 ( subtract 160 from both sides )

- x = - 58 ( multiply both sides by - 1 )

x = 58
