True.

Let's say that you have two pieces of paper that both represent planes. If you cross them, you'll be able to see that the intersection of these two pieces of paper is a line.

Find the angle between the given vector in degrees. u=<6, 4>, v=<7, 5> HELPPPPPPPPPP

Paladinen [302]

Recall that

$\vec a\cdot\vec b=\|\vec a\|\|\vec b\|\cos\theta$

where $\theta$ is the angle between the vectors $\vec a,\vec b$ whose magnitudes are $\|\vec a\|,\|\vec b\|$ , respectively.

We have

$\langle6,4\rangle\cdot\langle7,5\rangle=\sqrt{6^2+4^2}\sqrt{7^2+5^2}\cos\theta$

$\cos\theta=\dfrac{31}{\sqrt{962}}\implies\theta\approx88.2^\circ$

The measure of an angle is 12° less than twice the measure of its supplement. What is the measure of the angle?

kupik [55]

Here is the equation you should use: x + 2x - 12 = 180
You will be solving for x.

Combine like terms then add twelve to both sides of the equation.

3x = 192

Divide by 3 on both sides of the equation.

x = 64

Now, plug 64 in the equation for x.

2(64) - 12 = 116
