Answer:
Step-by-step explanation:
We can simplify this expression by combining like terms.
To combine like terms, we are looking for terms that share the same variable and exponent.
First, we can see that the terms and share the same variable (h) and the same exponent (2).
This simplifies to .
Next, we can see that and share the same variable (h) and the same exponent (1) so we can add these.
This simplifies to .
Lastly, we can see that we just have 7, no more terms with the same variable (none). So this is 7.
Adding up all the terms in standard form (), we get .

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.
