Answer:

AC = 4.15 is the answer.

Step-by-step explanation:

In the given triangle ABC the given parameters are side BC = 8.9

and the angle B is 25°.

We have to get the length of AC by using tangent values.

AS we know tan ∅ = Height/ Base

tan 25°= AC/BC

AC = BC × tan 25°

AC = 8.9 × 0.47

AC = 4.15

Therefore the length of the side AC = 4.15

Answer: AC=4.15

Step-by-step explanation:

To solve this problem you must apply the prccedure shown below:

1. You know that the triangle is a right triangle.

2. Therfore, you can calculate the lenght AC as following:

tan\alpha=opposite/adjacent

Where:

opposite=AC

adjacent=8.9

3. When you solve for AC and substitute these values you obtain the following result:

AC=8.9*tan(25\°)\\AC=4.15

ludmilkaskok [199]

Answer:

<h2>64 cm²</h2>

Step-by-step explanation:

given:

the scale from a square park to a drawing of the park is 5 m to 1 cm

the actual park has an area of 1,600 m²

find:

what is the area of the drawing of the park​

solution:

drawing scale is 5m : 1cm

<u>1,600 m² </u> = <u>      5² m²  </u>    

   x                  1² cm²

cross multiply:

5² m² x = 1600 m² (1 cm²)

x =<u> 1600 m² </u>

      5² m²

x = 64 cm²

therefore, the area of a square park in the drawing is 64 cm²
