10.) The lines that the angles are on are not parallel to each other. 11.) Angle 2 is also 60 degrees because they're corresponding angles. They're just on different lines but the place they meet the intersecting lines are the same. 12.) A real life situation that uses parallel lines are a rectangular room's walls that are parallel to each other.

Please help me with my math home work

Ket [755]

<u>page 1:</u>

$-\frac{8}{3} m = 6$

$-8m = 6(3)$

$-8m = 18$

$m = \frac{18}{-8}$

$m = -\frac{9}{4}$

$m = -2\frac{1}{4}$

<u>page 2</u>:

7)

$0.8x = 19$

$x = 19/0.8$

$x = 23.75$

8)

$0.12x = 1$

$x = 1/0.12$

$x =$ $\frac{25}{3}$

$x = 8\frac{1}{3}$

5)

3.3(x+4)

3.3x + 13.2

b.

$9-5\:\frac{1}{2}x-3\left(-2x+1\right)$

$9-\frac{11}{2}x-3\left(-2x+1\right)$

$6x-\frac{11}{2}x+9-3$

$x\frac{1}{2}+6$

$\frac{1}{2}x+6$

c.

$2.2(3.1+x)+3x$

$6.82+2.2x+3x$

$6.82+5.2x$

<u>page 3:</u>

1.

3/4 x = 60

x = (60*4)/3

x = 80

2.

2/5 x =42

x = (42*5)/2

x =105

3.

3/5 y = 40

y = (40*5)/3

y = $\frac{200}{3}$

y = $66\frac{2}{3}$

4.

$-\frac{8}{3}m =6$

$m = \frac{6*3}{-8}$

$m = -\frac{9}{4}$

$m = -2\frac{1}{4}$

5.

$\frac{5}{6} x =4$

$x = \frac{4*6}{5}$

$x =4.8$

6.

$\frac{5}{3} x =12$

$x = \frac{12*3}{5}$

$x =7.2$

Find the length of CA to the nearest tenth of a foot

hoa [83]

Answer:

CA ≈ 3.1 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan40° = $\frac{opposite}{adjacent}$ = $\frac{BC}{CA}$ = $\frac{2.6}{CA}$ ( multiply both sides by CA )

CA × tan40° = 2.6 ( divide both sides by tan40° )

CA = $\frac{2.6}{tan40}$ ≈ 3.1 ft ( to the nearest tenth )
