Step-by-step explanation:
as one angle is bigger than 90°
4x-3 ≥ 5
4x ≥ 5+3 (add 3 to both sides)
x ≥ 8/4 (divide both sides by 4)
x ≥ 2
a is the answer.
_____________________
3x-5 ≥ 7
3x ≥ 7+5
x ≥ 12/3
x ≥ 4
b is the answer
so, did you understand?
75.4 will be the answer..
as perimeter will be 2*pie*R
hope it helped
