Small triangle : (1,4), (3,1), (3,4)
The x: (3,2)
The big triangle: (-3,3), (-1,5), (-2,1)
(For the big triangle that is only correct if the black dot is the mirror line)
Answer:
1. (5x - 2) + (2x - 2) + x = 
2. m<J = 
3. m<K = 
4. m<L = 
Step-by-step explanation:
Generally, the sum of angles in a triangle =
.
So that;
m<J + m<K + m<L = 
(5x - 2) + (2x - 2) + x = 
5x + 2x + x -2 -2 = 
8x - 4 = 
8x =
+ 4
8x = 184
x = 
x = 
Thus,
m<J = (5x - 2)
= 5(23) - 2
= 
m<K = (2x -2)
= 2(23) - 2
= 
m<L = x
= 
Answer:
A U B = {1,2,3,4,5,6,8}
Step-by-step explanation:
Let's define the sets.
Let ¢ = universal set ( Contains all the elements in the set)
¢ = {1, 2, 3, 4, 5, 6, 7, 8, 9 , 10}
A= {2, 4, 6, 8}
B= {1,2,3,4,5,6}
Therefore: A U B (A union B):
A U B = {1, 2, 3, 4, 5, 6, 8}
