Answer:
t
Step-by-step explanation:
We have a line tangent to the circle with center B at point C. We know that the angle formed between the tangent line at the point of intersection to the line extended from that point to the center of the circle is equal to 90°. In the problem, the 90° is for ∠BCA. We also know that the summation of all angles in a triangle is 180°. We have the solution below for the ∠BAC
180°=∠BAC + ∠BCA + ∠ABC
180°=∠BAC + 90° + 40°
∠BAC =50°
The answer is 50°.
Six dozen cupcakes is 72. So in this case Kailyn made 88 cupcakes, but that was 72 more than Melissa made so Melissa only made 16.
Answer:
The likelihood that a point chosen inside the square will also be inside the circle: 78.54%
Step-by-step explanation:
- Let x is the side of the suqare
=> the area of the square is: 
- Let d is the diameter of the circle
=> the area of the circle :
π
However, d=x because of the square property
<=> the area of the circle :
π
The likelihood that a point chosen inside the square will also be inside the circle:
the area of the circle / the area of the square
=
π /
=
π *100%
= 0.7854 * 100%
= 78.54%
