Answer:
See explanation
Step-by-step explanation:
The given circle has center O.
A, B,C, and D are points on the circumference of the circle.
We want to prove that: 
We need to join to B and C as shown in the attachment.
Recall that angle subtended by arc BC at the center is twice the angle subtended at the circumference by the same arc.
This implies that:


The LHS of equation (1) and (2) are equal. Therefore the RHS are also equal.
This implies that:


Answer:
1-5n
Step-by-step explanation:
you would do 1-5n because its in brackets, the order of opperation is
Brakcets
Order (Power ofs)
Division and Mulitplication
then do addition and subtraction
when doing division and multiplication and subtraction and addition go left to right to find what part goes 1st.

Answer:
1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(3-(-1))/(2-(-2))
m=(3+1)/(2+2)
m=4/4
m=1
Hi!
(l = Lenny
m = Max)
Lenny is 3 times as old as Max.
3m = l
When you subtract Max's age from Lenny's age, you get 24.
L - m = 24
Put in the value of l.
3m - m = 24
There is our equation.
Now solve
2m = 24
2m/2 = 24/2
m = 12
3 * 12 = l
36 = l
The equation is 3m - m = 24
Max is 12 and Lenny is 36.
Hope this helps! :)
