Answer:
7*3x=18
-7 -7
3x=11
3x/3 11/3
x=3.67
Step-by-step explanation:
The answer is angle JKL is 54 degrees
4(3+5) --> this means that 12/4=3 and 20/4=5 and 4 is the GCF
When reflecting across the Y axis, the Y values remain the same.
Now if you were reflecting across Y = 0, the x values would just be inverse ( opposite signs).
So this triangle if reflected across Y = 0 the new vertices would be (4,4) (2,3) and (5,2)
Now since the reflection line is y = -1, which is a one unit shift to the left of y = 0, subtract 1 unit from each X value.
The locations are now: A'(3,4), B'(1,3) and C'(4,2)
Answer:
SA = 838 in²
Step-by-step explanation:
SA = (15)(42) + (13)(8)(2) = 838 in²
