If triangle abc is similar to triangle edc find the value of x

Mathematics
1 answer:
svetoff [14.1K]2 years ago
4 0

Answer:

x = 15

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{BC}{DC} = \frac{AC}{EC} , substitute values

\frac{3x-5}{32} = \frac{5x-5}{56} ( cross- multiply )

56(3x - 5) = 32(5x - 5) ← distribute and simplify both sides

168x - 280 = 160x - 160 ( subtract 160x from both sides )

8x - 280 = - 160 ( add 280 to both sides )

8x = 120 ( divide both sides by 8 )

x = 15

(7.99 × 7/3) and 18.64

This is further explained below.

<h3>What is expressions ?</h3>

In most cases, the two expressions that are comparable to one another for the total cost of the cloth are

(7.99 × 7/3) and 18.64

Total cost = Cost of fabric per yard * Number of fabrics

= 7.99 × 2 1/3

= (7.99 × 7/3)

= 55.93 / 3

= 18.64

As a result, the two expressions that are comparable to one another for the total cost of the cloth are and

(7.99 × 7/3) and 18.64

In two or more complete sentences explain how you would set up and solve the equation: Dan and Rick belong to different gyms. Da
olga55 [171]
The equation would be 40+15p=70+5p. You would subtract 5p from each side (15-5) and (5-5) and you'll have 40+10p=70. You would then subtract 40 from each side (70-40) and (40-40) to have 10p=30. You would divide by both of the sides by 10, you would end up with p=3. P is price training. The reason you divide and subtract on both sides is because you want the months to be on one side and the price training on the other side.
