The perimeter of an equilateral triangle is 63 inches. If the length of each side is (4x-3), find the value of x. Equilateral me

vladimir2022 [97]

Answer:

Step-by-step explanation:

3*(4x - 3) = 63 Divide both sides by 3

4x - 3 = 63/3

4x - 3 = 21 Add 3 to both sides

4x = 21 + 3

4x = 24 Divide by 4 on both sides

4x/4 = 24/4

x = 6

Note: The perimeter is the sum of all three sides. One side is 4x - 3 All 3 sides must be 3*(4x - 3)

Which theorem or postulate proves the two triangles are similar?

Andre45 [30]

Answer:

The corresponding pair of sides are in the same ratio.

Step-by-step explanation:

For two triangles to be similar, the theorem that is required is the corresponding sides of the two triangles are in the same ratio.

Now, see the diagram of two triangles given with the question.

The ratios of the corresponding sides are $\frac{20}{16} = \frac{19}{\frac{76}{5} } = \frac{5}{4}$

If two pairs corresponding sides are in 5 : 4 ratio, then the third pair of corresponding sides will also be in 5 : 4 ratio.

Therefore, the two triangles are similar. (Answer)
