Part 1)
we know that
the property of cyclic quadrilaterals for which opposite angles are supplementary
then
m∠A°+43°=180°------------> m∠A=180°-43°=137°
the answer is m∠A=137°
Part 2) <span>Quadrilateral ABCD is inscribed in a circle. What is the measure of angle A?
we know that
</span>the property of cyclic quadrilaterals<span> for which opposite angles are supplementary
then:</span>
<span>m∠A+m∠C=<span>180<span>∘
(2x+9)+(3x+1)=180---------------> 5x+10=180
x=(180-10)/5=34
</span></span></span>m∠A=2x+9-------------> 2*34+9=77°
<span>
the answer is </span>m∠A=77°<span>

Answer:
B
Step-by-step explanation:
If Sean wants to but both the muffin and cookie then this addition. 3 +m shows the correct expression. the answer is b
Answer: Choice B and D are both correct.
Step-by-step explanation:
The expression has two adjacent negative signs in the middle. The two negative signs are to be multiplied, which then produces one positive sign.
Choice B is therefore correct because the expression becomes 6+6 which is 6 to the right of the number line where the numbers are increasing.
Choice D is also equally correct because the addition of 6 to 6 equals 12(6+6 = 12).
You'll have to set up a proportion.

Answer:
Taking that you didn't provide any other information about the values of x..
The only plausible answer, which probably isn't your case but still can be valid out of context is 19.
Step-by-step explanation:
"X" is 10 in Roman numbers.
9 + 10 = 19
(But I suppose that you had more details to the question that you didn't yet share :) )
OR.. the answer might be an algebraic expression..
