There are two triangles that exist in this problem. First is the given triangle ABC, witch AB = BC = 6 and AC = 8
Next is the smaller triangle formed by connecting points D and E; triangle EAD, with EA = AD = 3 and the length of DE is unknown.
Because these triangles are similar, a simple ratio may be set up in order to calculate DE.
DE / AC = EA / AB
DE = 3/6 * 8
DE = 4 units

Answer:

here are two triangles that exist in this problem. First is the given triangle ABC, witch AB = BC = 6 and AC = 8

Next is the smaller triangle formed by connecting points D and E; triangle EAD, with EA = AD = 3 and the length of DE is unknown.

Because these triangles are similar, a simple ratio may be set up in order to calculate DE.

DE / AC = EA / AB

DE = 3/6 * 8

DE = 4 units

The larger of two numbers is four more than the smaller number.If the sum of the numbers is 61,find the numbers
sergij07 [2.7K]

Answer:

<u>28.5 and 32.5</u>

Step-by-step explanation:

<em>create an equation to solve:</em>

x + (x+4) =61

2x + 4 = 61 combine like terms

2x = 57 subtract 4 from both sides

x = 28.5 divide 2 from both sides

28.5 is the smaller number

the larger number is 4 more so:

28.5 + 4 = 32.5

32.5 is the larger number

check your work:

28.5 + 32.5 = 61

What is the length of the hypotenuse? If necessary, round to the nearest tenth.

Without rounding to the nearest tenth, it would be 7.28. Rounding it would give you with an answer of 7.3 with rounding.
