Answer:
Step-by-step explanation:
1). Since, XM is the radius of the circle,
Therefore, area of the circle = 
= 
= 
= 452.39 units²
2). Circumference of a circle = 2πr
= 2π(XM)
= 2π(12)
= 24π
= 75.40 units
3). By applying Pythagoras theorem in ΔYXM,
YM² = XY² + XM²
(43)²= (XY)² + (12)²
1849 - 144 = (XY)²
XY = 41.29 units
4). tan(∠M) =
= 
m∠M = 
= 73.79°
5). Area of ΔXYM = 
= 
= 247.74 square units
6). Area of the minor sector created by ΔXYM = 
= 
= 92.73 units²
D. You define if a quadratic equation has an answer or not by the delta (the calculation inside the sqrt on the quadratic formula). So you simply calculate b^2 -4ac, if the answer is equal or greater than zero there is a solution, if not there isn’t. (Consider ax^2+bx+c) Hope it helped :)
3/4 is 6/8 and 7/8 is 7/8 so also is 6/7 i hope it helped u
