Remember that complementary angles add to 90 degrees.

so therefor, you can find the complement of m<A by solving 

90 - 77 = A

A = 13 degrees

^^^ This explains the second part.

The compliment of a compliment can be found by subtracting the known compliment from 90 :)

Answer:

1) Complement = 90 - 77 = 13⁰

2) We can conclude that complement of complement of any angle is the angle itself

Barbara is tilling here craft room with square tiles , she wants 6/10 of the square to be red if she uses 18 red tiles how many
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

The position of an open-water swimmer is shown in the graph. The shortest route to the shoreline is one that is perpendicular to
marin [14]

Answer:

An equation that represents this path is described below in detail.

Step-by-step explanation:

The equalization that describes the pathway of the swimmer to the shoreline can be described in the slope-intercept pattern, given as.

Where,

Slope (m) = the adverse reciprocal of the incline of the shoreline, considering it is perpendicular to it = ??

y-intercept (b) = ??

Find the incline of the shoreline using, (0, 1) and (4, 4):

.

Considering the incline of the shoreline is ¾. The incline of the pathway of the swimmer would be the adverse reciprocal of ¾.

The adverse reciprocal of ¾ = -⁴/3.

The incline of the swimmer's path = -⁴/3.

Applying the coordinate of the position of the swimmer (6, 1), and the incline of the way, we can find b, the y-intercept of the way.

Substitute x = 6, y = 1 and m = -⁴/3 into y = mx + b, to find b.

Thus:

1 = (-⁴/3)(6) + b

1 = -8 + b

Add 8 to both sides

1 + 8 = b

9 = b

b = 9

Substitute m = -⁴/3 and b = 9 into y = mx + b.

Answer:

84 ft^2

Step-by-step explanation:

Rectangle 1: Area = l x w = 3x6=16

Rectangle 2: 4x6= 24

Rectangle 3: 5x6=30

Triangle 1: A = 1/2 b x h = 1/2 x 4 x 3 = 6

Triangle 2: 1/2 x 4 x 3 = 6

Total = 16+24+30+6+6 = 84
