Step-by-step explanation:
yes the are similar because of AA Theorem
EAB is similar to ECD
Complementary angles add up to 90 degrees.
Which means.. the equation is
8x-23+7x-7=90
Combine like terms you should get
15x-30=90
Add 30 on both sides
15x=120
Divide 15 x=8
Plug in 8 to (8x-23)
8(8)=64-23=41
m
Answer:
3 2/3
Step-by-step explanation:
7 1/6 - 3 1/2= 3 2/3
120/2=60 (sum of both lengths)
4x+4=60
4x=56
x=14
length=46
width=14
Answer:
Step-by-step explanation:
If you draw a line from the origin (0,0) to L ( the original point ) and a different line from the origin to the image L' you can see the angle of rotation as being
90 degrees and that the rotation is clockwise.
the rule is (x, y) become ( y, -x)
