Answer:
8x + 12 = 12 + 8x
0 = 0
Step-by-step explanation:
Distribute then simplify
We know that
scale factor=measure larger triangle/measure smaller triangle---->18/12
scale factor=1.5
so
measure larger triangle=scale factor*measure smaller triangle
for the leg in the smaller triangle equal to 5
measure larger triangle=1.5*5-----> 7.5
the answer is
7.5
Sorry if its illegible, you can ask if its not clear
-28+2r+3r+5
simplified it is -23+5r
Supplements add up to 180°
so just subtract 164 from 180
180
<u>-164
</u> 16
