Each pair of polygons below is similar. Find the value of x. Some answers may be decimals.

sergiy2304 [10]

Answer:

The answer to your question is below.

Step-by-step explanation:

14.- Use proportions to solve these problems.

$\frac{x + 6}{10} = \frac{x + 9}{14}$

14(x + 6) = 10(x + 9)

14x + 84 = 10x + 90

14x - 10x = 90 - 84

4x = 6

x = 6/4

x = 3/2

15.- $\frac{x - 1}{8} = \frac{x + 2}{10}$

10(x - 1) = 8(x + 2)

10x - 10 = 8x + 16

10x - 8x = 16 + 10

2x = 26

x = 26 / 2

x = 13

16.- $\frac{x + 1}{9} = \frac{10/3}{5}$

5(x + 1) = 9(10/3)

5x + 5 = 30

5x = 30 - 5

5x = 25

x = 25 / 5

x = 5

Given ƒ(x) = −3x + 21, find x when ƒ(x) = 6. A) −2 B) 3 C) 5 D) 7

vagabundo [1.1K]

Answer:

x = 5

Step-by-step explanation:

We have,

$f(x) = -3x + 21$ .....(1)

It is required to find x when the value of f(x) = 6

Put f(x) = 6 in equation (1) such that we get :

$6 = -3x + 21\\\\3x=21-6\\\\3x=15\\\\x=5$

The value of x is 5 if f(x) = 6.

Find the measures of the angles labeled in the figure.

vitfil [10]

m<EFD=90°.

#2

$\\ \rm\longmapsto H+55=180$

$\\ \rm\longmapsto H=180-55=125$

#3

$\\ \rm\longmapsto b+35=90$

$\\ \rm\longmapsto b=90-35=55$

#4

$\\ \rm\longmapsto a+55+55=180$

$\\ \rm\longmapsto a=180-110$

$\\ \rm\longmapsto a=70$

#5

Now using angle sum property .

$\\ \rm\longmapsto d+125+35=180$

$\\ \rm\longmapsto d=180-160$

$\\ \rm\longmapsto d=20°$
