Answer:
coordinates of A are (11/2, -3/2)
Step-by-step explanation:
midpoint = M(5, −4)
start point = A(6, 1)
endpoint = B(x, y)
equation :
x = m1 × x2 + m2 × x1 y = m1 × y2 + m2 × y1
_____________ _____________
m1 + m2 m1 + m2
x = (1 × 6) + (1 × 5) y= (1 × 1) + (1 × -4)
_____________ ____________
1 + 1 1 + 1
x = (6+5 )/ 2 = 11 / 2 y = (1+(-4))/2+(1-4)/2 = -3/2
∴coordinates of A are (11/2, -3/2)
i think u should view this on a wider screen if ur using a phone <3

This is what is in the middle of the second paragraph. That statement is correct.
I don't know that it is any simpler or not, but what they have done in the answer is rationalize the denominator. That means that the denominator is no longer under the square root sign.
To get that result, you multiply numerator and denominator by √F
When you do that, your get

This results in the middle answer.

Answer:
3/45
Step-by-step explanation:
To find the numerator, multiply the desired denominator by the fraction.
x/45 = 1/15
x = (45)(1/15) = 45/15 = 3
The equivalent fraction is 3/45.
The inscribed triangle is a right triangle. The diameter of the circle served as the hypotenuse of the triangle.
Angle C is 90°
Angle D = 36°/2 = 18°

180° - 90° - 18° = 72°
Remember that interior angles of a triangle sum up to 180°.
