An isosceles triangle has a base 9.2 units long. If the congruent side lengths have measures to the first decimal place, what is
Nadusha1986 [10]

Question:

An isosceles triangle has a base of 9.6 units long. If the congruent side lengths have measures to the first decimal place, what is the possible length of the sides? 9.7, 4.9, or 4.7

Answer:

4.9 is the shortest possible length of the sides.

Step-by-step explanation:

Given:

The base of the triangle base  =   9.2 units

To Find:

The shortest possible length of the sides = ?

Solution:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

So According to the theorem

x+x > 9.6

2x > 9.6

x > \frac{9.6}{2}

x > 4.8

In the given option 4.9 is the shortest length greater than 4.8 that can be possible.

Please help me this is a hard problem
Levart [38]

Step-by-step explanation:

- 3y + 10 = x...(1) \\ 10x + 7y =  - 38...(2) \\ from \: equations \: (1) \: and \: (2) \\ 10( - 3y + 10) + 7y =  - 38 \\  - 30y + 100 + 7y =  - 38 \\  - 23y =  - 38 - 100 \\  - 23y =  - 138 \\ y =  \frac{ - 138}{ - 23}  \\  \huge \red { \boxed{y = 6}} \\ substituting \: y = 6 \: in \: equation \: (1) \\ x =  - 3 \times 6 + 10 =  - 18 + 10 =  - 8 \\   \huge \red { \boxed{x =  - 8}} \\  \\  \:  \:  \huge \purple{ \boxed{(x, \:  \: y) = ( - 8, \:  \: 6)}}
