Answer:
x=78°
y=78°
z=102°
Step-by-step explanation:
x=78°
y=78°
z=180-78=102°
(5,7)
translate down by 4:
(5,3)
reflect over y (so invert x-coordinate):
(-5,3)
<span>-9 -10[7x -3(3 + 10x)]
= -9 - 10(7x - 9 - 30x)
= -9 - 10( -23x - 9)
= -9 + 230x + 90
= 230x + 81
Answer: </span>230x + 81<span>
</span>
You get an answer of x=10 from solving the equation, which is extraneous so there is no solution. see work attached
