X+2.6=1.7
x+12=7
x+12-12=7-12 (subtract 12 from both sides)
x=-5
The measure of angle bcd of the polygon abcd is 40°.
Hence, option b) 40° is the correct answer.

What is a polygon?</h3>
A polygon is simply a two-dimensional a plane shape enclosed by line segments called sides.
The sum of the exterior angles of a regular polygon will always equal 360
Given that;
- Exterior angle a = 25 degrees
- Exterior angle b = 146 degrees
- Exterior angle d = 149 degrees
25° + 146° + 149° + c = 360°
320° + c = 360°
c = 360° - 320°
c = 40°
The measure of angle bcd of the polygon abcd is 40°.
Hence, option b) 40° is the correct answer.

Answer:
Step-by-step explanation:
The equation is mx+b=y.
M=slope (in this case 5)
x=x coordinates
b=y intercept
y=y coordinates
For the x and y coordinates, I'll use (2,0).
5(2)+_=0
10+_=0.
In this case, we only have one awnser, -10. Since 10+(-10) are the only ways to equal 0.
Hope this helps,
Given:
Jake bought 3 drawing pens for $8.07.
Each pen costs the same amount.
To find:
How much did he spend for one pen?
Solution:
Let x be the cost of each pen. Then
Cost of three pens = 3x
Jake bought 3 drawing pens for $8.07.

Divide both sides by 3.


Therefore, he spend $2.69 for one pen.
Option B i.e. Non-Euclidean
