ANSWER
T(-2,1)
EXPLANATION
Let T(a,b) be the coordinates.
When this point is rotated 90° counterclockwise about the origin,
Then,

If this point is then translated using the rule;

then,

It was given that, T"(-2,5)
This implies that,
-b-1=-2
-b=-2+1
-b=-1
b=1
a+7=5
a=5-7
a=-2
Therefore the coordinates of T are:
(-2,1)
Answer:
68º
Step-by-step explanation:
This is a quadrilateral and all degrees in every quadrilateral have to add up to 360º.
81º + 135º + 76º = 292º
360º - 292º = 68º
Therefore, x = 68º
