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:
I'm leaning mostly towards C Because there is a solution, None of them are real numbers and if they were, S would = 5 Especially positive S

Answer:
<em>x = 30°, and y = 46°</em>
Step-by-step explanation:
If we take a look at the attachment below, we will find x = 30°, and y = 46°;
Answer:
The answer to your question is Center = (-5, 1) radius = 2
Step-by-step explanation:
Data
(x + 5)² + (y - 1)² = 4
Here we have the standard form of a circle. In the standard form, the center is represented as C (h, k). As the formula below
(x - h)² + (y - k)² = r²
Then,
h = -(5) = -5
k = -(-1) = 1
and radius = r = 2 r² = 4
Conclusion
Center = (-5, 1) radius = 2
