Answer:
y = 56
Step-by-step explanation:
the midsegment SV is half the length of the side TU , that is
y - 9 = 
(y + 38) ← multiply both sides by 2 to clear the fraction
2y - 18 = y + 38 ( subtract y from both sides )
y - 18 = 38 ( add 18 to both sides )
y = 56
Answer:
√357
Step-by-step explanation:
multiply all three numbers together and since 357 cannot be simplified it stays as a radical
After rotation the output for point C´ would be ( - 2 . -3 ). There is also a graph showing rotation in the attachment.
52+23=75
10+78=88
88+75=163
that's one way
