The coordinated of the preimage would be :
x = x cos θ + y sin θ
y = x sin θ + y cos θ
where
x = -4
y = 7
θ = -90
hope this helps
Answer: x=136 degrees
Step-by-step explanation: All 3 angles inside a triangle added together will get you 180 degrees. 46+90 degrees is 136. 180-136=44 degrees. Now a line is 180 degrees too. 180-44=136 degrees for x.
Answer:
The answer is >.
Step-by-step explanation:
78 19/88 is bigger than 74/93 because 74/93 has way less whole numbers on its side.


Use quadratic formula to solve (shown in picture):
We would get two answers:
