∠1 and ∠2 are supplementary.

1 answer:

6 0

Supplementary means the 2 angles add up to 180 so...

124+(2x+4)=180

124+2x+4=180

124+2x+4-4=180-4

124+2x=176

124-124+2x=176-124

2x=52

2x/2=52/2

x=26
plug in and check

124+2x+4=180

124+2 (26)+4=180

124+52+4=180

176+4=180

180=180

irina1246 [14]

Answer:

30square tiles will be used to cover the floor

Step-by-step explanation:

Given:

Number of tiles to be red = 6/10

Total number of tiles used =18

To Find:

how many square tiles will be used to cover the floor = ?

Solution:

Let the number of square tile used to cover the floor be x

Then

$x \times \frac{6}{10} =18$

$x =\frac{18}{\frac{6}{10}}$

$x = \frac{18 \times 10}{6}$

$x = \frac{180}{6}$

x = 30
