An isosceles triangle has a base 10 units long. If the congruent side lengths have measures to the first decimal place, what is the shortest possible length of the sides?

5.1 units

Step-by-step explanation:

At first we should know that, the sum of the lengths of any two sides of a triangle is greater than the length of the remaining side.

Given: An isosceles triangle has a base 10 units long.

Let the length of each side of the congruent sides = x

So, x + x > 10

2x > 10

x > 5

the congruent side lengths have measures to the first decimal place,

So, the congruent side lengths have measures to the nearest tenths.

So, the shortest possible length of the sides = 5.1 units

their are no angles. sorry cant .

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.
