Work out the size of angle x <br> Next to 164 and 90

Zielflug [23.3K]

Answer:

x=106 degrees

Step-by-step explanation:

I'm going to assume that this is a circle since you didn't give it to me

So you want to add 164 and 90 together and subtract the sum by 360

360-(164+90)=106

So you want to use PEMDAS (order of operations) to solve this

so do what's in the perenthesis first so 164+90=254
Then you want to subtract 254 from 360 so 360-254=106

x=106 degrees

Which of these statements best describes the relation shown in Item 1?

Misha Larkins [42]

Answer:

It is a many-to-one relation

Step-by-step explanation:

Given

See attachment for relation

Required

What type of function is it?

The relation can be represented as:

$\left[\begin{array}{c}x\\ \\-5\\-2\\1\\5\end{array}\right]$ $\left[\begin{array}{c}y\\ \\10\\11\\4\\10\end{array}\right]$

Where

$x = domain$ and $y = range$

Notice that the range has an occurrence of 10 (twice)

i.e.

$(x_1,y_1) = (-5,10)$ and $(x_2,y_2) = (5,10)$

In function and relations, when two different values in the domain point to the same value in the range implies that, <em>the relation is many to one.</em>
