Answer:
x<5
Step-by-step explanation:
2x-3>7 you add three to both sides
2x>10 you then divide 2x by 2 and 10 by 2 which switches the symbol around
x<5 that's the answer
Where is the figure?or is there not
We know all the side lengths so can use law of cosines. a=90, b=55, and c=50.
2500=8100+3025-2(90)(55)cos(C)
cos(C)=.8712
C=arccos(.8712)=29.4 degrees
The answer is C. 45. Here's the work to prove it: c = correct answer, i = incorrect answer;
-2(c + i = 50)
2c - 3i = 75
-2c - 2i = -100
-5i/-5 = -25/-5
i = 5
c + 5 - 5 = 50 - 5
c = 45
