We know that
A quadrilateral is inscribed in a circle if and only if the opposite angles are supplementary. ( Inscribed Quadrilateral Theorem)
so
m∠B+m∠D=180°
2x+(3x-5)=180
5x=180+5
5x=185
x=185/5
x=37°
m∠A=x+5-----> 37+5------> 42°
the answer is
m∠A is 42°
Answer:
6 2/3 cups needed
Step-by-step explanation:
So first I would find the unit rate for cookies and cups
1 cup = 9 cookies
So now divide becuase we want to find the amount of cookies
60/9= 6.666666666 or 6 2/3
Now normally it would just be left like that
Answer:
zero triangles. No triangle can be formed with angles measuring 70°, 70° and 70°
Explanation:
In any triangle (regardless its type), the sum of the interior angles should always be 180°.
Now, assume we have 3 angles each measuring 70°.
Sum of these three angles = 70 + 70 + 70 = 210° which is greater than 180.
Since we mentioned that the sum on interior angles MUST be 180, therefore, the given measurements cannot be combined to form a triangle.
Hope this helps :)
