Here you go love. I worked out the problem and showed the word answers :)
The value of nine is 90,000.
Hope that helped:)
Answer:
7/2 or 3 1/2
Step-by-step explanation:
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.

<span>When you multiply numbers, two negative signs cancel each other out. Therefore if four of the numbers are negative the product is positive. If either one or three numbers are negative, the product is negative.
1.a negative, b positive, c positive, d positive
2.a positive, b negative, c positive, d positive
3.a positive, b positive, c negative, d positive
4.a positive, b positive, c positive, d negative
5.a positive, b negative, c negative, d negative
6.a negative, b positive, c negative, d negative
7.a negative, b negative, c positive, d negative
8.a negative, b negative, c negative, d positive</span>
