The perimeter of an isosceles triangle is 25 ft. the length of the third side is 2 ft less than the length of one of the equal sides. find the measurement of the three sides of the triangle.

The side lengths are 9, 9 and 7.

Step-by-step explanation:

The sum of the 2 equal sides plus the shorter side is 25 ft.

Representing these unknowns:

2 sides are of length s, and the third (shortest) side is then s - 2.

Thus,  s + s + (s - 2) = 25, or 3s = 27.  Thus, s = 9 and s-2 = 7

The side lengths are 9, 9 and 7.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

c. side angle side. u shares the same sides
