The sum is 
<em><u>Solution:</u></em>
Given that we have to find the sum
<em><u>Given expression is:</u></em>

We have to add both the expressions
Addition of two polynomials involves combining like terms present in the two polynomials
Like terms are the terms having same variable and same exponent
From given expression,

Remove the parenthesis and add

Combine the like terms

Add the like terms

Thus the sum is 
Answer:
B. 44°
Step-by-step explanation:
Central angle = 3x + 10°
Inscribed angle = 2x - 17°
Now
Central angle = 2 * inscribed angle
( Central angle is double of the inscribed angle standing on same arc)
3x + 10° = 2 ( 2x - 17°)
3x + 10° = 4x - 34°
4x - 3x = 34 ° + 10°
x = 44°
Hope it will help :)❤
3x-r=-3r+rx
3x=-3r+r+rx
3x=-2r+rx
3=rx-2r/x
there you go buddy...gitty up
It would be: 6/9 = 2/3 = 2 : 3
In short, Your Answer would be Option B
Hope this helps!
