A B C ~ A D E: find x

A B C ~ A D E: Find X

Answers

Answer 1

Answer:

[tex] \frac{20}{28} = \frac{15}{2x + 3} \\ 20(2x + 3) = 15 \times 28 \\ 40x + 60 = 420 \\ 40x = 420 - 60\\ 40x = 360 \\ x = 9[/tex]

Answer 2

The value of x using the proportionality rule is 9.

What are Similar Triangles?

Two triangles are said to be similar if the triangles are of the same shape but different size. The angles of the triangle will be equal and the sides are proportional.

Given that the two triangles ABC and ADE are similar triangles.

We have to find the value of x.

If two triangles are similar, then the corresponding sides are proportional.

A corresponds to A, B corresponds to D and C corresponds to E.

AB / AD = BC / DE = AC / AD.

Consider AB / AD = BC / DE.

28 / 20 = 2x+3 / 15

Cross multiplying,

20 (2x + 3) = 28 × 15

2x + 3 = 21

2x = 18

x = 9

Hence the value of x is 9.

What is the value of y when x is 16?

in order to do this problem, you have to divide 16 by 2 to see how many times x was multiplied. you would find that x was multiplied 8 times, so in order to find y, you would multiply 3.5 eight times.

I just need help on these two questions ​

Answers

Answer:

Q1) y= 2

Q2) y= 4

Step-by-step explanation:

Q1) If you sub in x as -1, 2 to the power of -1 is 0.5. You always solve the power first, not the multiplication. So then you do 0.5 times 4 and you get 2.

Q2) If you sub in x as 0, anything to the power of 0 becomes 1. 2 to the power of 0 is 1. Then you do the multiplication, 4 times 1 = 4
