HELP HELP HELP PLEASE HELP!!!!!!!!!!!!!! I NEED HELP!!!!!!!!!!!!!!!!!!

____ [38]

This is a relatively easy question if you know a couple things, so let me walk you through this step by step ok?

<em>Answer: 115°</em>

<h3>Sum of interior angles of a pentagon: 540°</h3>

Now with that said:

Your first step is to add all of the interior angles together, and then subtract it from the total sum of the interior angles of the shape that your working with.

If you don't know what the sum of all of the interior angles are for the shape you are working with, you can easily look it up on google to be sure.

<em>If you have anymore questions, </em>Don't be afraid to ask! I'm always glad to help, also if I am wrong please let me know and I promise I will come back and rework my math.

<h2>Thanks!</h2>

X - 2 = 16<br><br> A. 14<br> B. 18<br> C. 21<br> D. 12

Vlada [557]

X=18
Because you would add 2 to both sides so it would be x=16+2 which equals 18

Here are the monthly charges for jo’s Mobile phone. Monthly charge £16,150 free minutes,then 13p per minute,150 free texts,then

xz_007 [3.2K]

Jo's Mobile Plan:

Fixed monthly charge = £16
Monthly 150 free minutes, post that 13p (or £0.13) per minute,
Monthly 150 free texts, post that 15p (or £0.15) per text

Jo's mobile phone usage details:

170 minutes of calls
182 texts

Total Charges for Jo = Fixed Monthly Charge + Charges for Calls + Charges for Texts

⇒ Total Charges for Jo = 16 + (170-150) × 0.13 + (182-150) × 0.15

⇒ Total Charges for Jo = 16 + (20) × 0.13 + (32) × 0.15

⇒ Total Charges for Jo = 16 + 2.6 + 4.8

⇒ Total Charges for Jo = 23.4

Hence, Jo should be charged £23.4 for the month.

Question 1: On a coordinate plane, triangle ABC has vertices at A(10,5), B(10,15), and C(5,5). Triangle A'B'C' has vertices at A

Vilka [71]

Answer:

B. (x,y) --> (4x - 10, 4y - 8)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, dilation and rotation.

If a point X(x, y) is translated a units right and b units up, the new location is (x + a, y + b) also If a point X(x, y) is translated a units left and b units down, the new location is (x - a, y - b)

If a point X(x, y) is dilated by the factor k the new location is X'(kx, ky).

Triangle ABC has vertices at A(10,5), B(10,15), and C(5,5), If it is dilated by a factor of 4, the new location is A*(40, 20), B*(40, 60) and C*(20, 20). If then a translation of 10 units left and 8 units down, the new points are A'(30, 12), B'(30, 52), C'(10, 12).

This is a transformation of (x,y) --> (4x - 10, 4y - 8)
