Complementary angles are angles whose sum is equal to 90 degrees. The cosine of an angle is equal to the sine value of its complementary. In this case, the complementary of 47 degrees is 43 degrees. Hence cosine 47 should be equal to sin 43. That is letter B

Fatima is shaping this model to show 0.08 x 3. shade the correct amount of boxes that will show the product. fatima should shade
julia-pushkina [17]

Answer:

Fatima should shade 3 groups of 8 small squares or 24  small squares.

Step-by-step explanation:

Consider the provided information.

Fatima is shading this model to show 0.08 × 3. Shade the correct  amount of boxes that will show the product.

Here 3 represents the number of groups and 8 represents the small square.

Multiplication is repeated addition.

We can rewrite the above multiplication as: 0.08 + 0.08 + 0.08

Therefore 0.08 × 3 = 0.24

Here 0.24 represents 24 small squares.

The required model is shown below:

Hence, Fatima should shade 3 groups of 8 small squares or 24  small squares.

Please help it will be brainlist please make sure you are 100% the awnser is right
Dominik [7]

Answer:

Step-by-step explanation:

Step 1: Sum of angles on a straight line is 180

Step 2:

2x + 25 + y = 180

2x + y = 180 - 25

2x + y = 155  (1)

Step 3:

3x - 10 + y = 180

3x + y = 180 + 10

3x + y = 190    (2)

Step 4: Substract equation 1 from 2

3x + y - 2x - y = 190 - 155

      x = 35

Step 5:

Substitute x in equation 1 to find y

2x + y = 55

2(35) + y = 155

70  +  y = 155

  y = 155 - 70

   y = 85
