Jenny earned a 77 on her most recent test. Jenny’s score is no less than 5 points greater than Four-fifths of Terrance’s score.
If t represents Terrance’s score, which inequality represents the situation? 77 greater-than 5 + four-fifths t
77 greater-than-or-equal-to 5 + four-fifths t
77 less-than 5 + four-fifths t
77 less-than-or-equal-to 5 + four-fifths t
The value of the length of the rhombus will be found as follows: cos θ=adjacent /hypotenuse θ=108/2=54° adjacent = 9/2=4.5 inch hypotenuse=length of the rhombus thus cos 54=9/x x=4.5/cos 54 x=7.6558~8 inches the answer is 8 inches
