Answer:
The measure of the side AB is 26 cm.
Step-by-step explanation:
The question is:
In a triangle ABC the hypotenuse BC measures 30 cm, it is known that the angle of the opposite angle to the side AB, measures 60°, therefore it is concluded that as side AB the triangle measures ?
Solution:
Consider the triangle ABC.
The side BC is defined as a hypotenuse. This implies that the triangle ABC is a right angled triangle.
The angle A measures 90° and the angle C measures 60°.
The hypotenuse length is 30 cm.
According to the trigonometric identities for right angled triangle:
Compute the length of side AB as follows:
Thus, the measure of the side AB is 26 cm.
Answer:
- Heather's model represents the greater area.
greater.
Step-by-step explanation:
The formula for calculate the area of a rectangle is:
Where "l" is the lenght of the rectangle and "w" is the width.
The formula for calculate the area of a square is:
Where "s" is the side lenght.
In this case, knowing that Elle's model represented 20 feet by 15 feet, we can say that:
Therefore, substituting these values into the formula , we get that the area is:
Since Heather's model represented 18 ft by 18 feet, we can identify that:
Substituting this value into , we get this area:
Notice that Heather's model represents the greater area.
To calculate how much greater it is, subtract the areas. Then:
