Answer:
1. an isosceles triangle
2. SAS information is known
3. 7.35
4. 72 degrees
5. 13. ft
Step-by-step explanation:
The bottom side of the flag measures 5 feet because the triangle is AN ISOSCELES TRIANGLE . Because SAS INFORMATION IS KNOWN, the trigonometric triangle formula is used to calculate that the area is (5)(5)sin(36°) ≈ 7.35 square feet. Recalling that this triangle is isosceles, we can write the area equation to solve for x.
7.35 = 1/2(x)(5)sin(72 DEGEREES).
Solving for x and adding this value to the length of the other sides, the perimeter ≈ 13.1 FT (rounded to the nearest tenth).
The bottom side of the flag measures 5 feet because the triangle is an isosceles triangle.
Because SAS information is known the trigonometric triangle formula is used to calculate that the area is (5)(5)sin(36°) ≈ 7.35 square feet.
Recalling that this triangle is isosceles, we can write the area equation to solve for 7.35 = (x)(5)sin(72).
The length of the other side of the perimeter is 3.
Given that
The bottom side of the flag measures 5 feet because the triangle is.
Because the trigonometric triangle formula is used to calculate that the area is (5)(5)sin(36°) ≈ 7.35 square feet.
Recalling that this triangle is isosceles, we can write the area equation to solve for x. = (x)(5)sin().
Solving for x and adding this value to the length of the other sides, the perimeter.
We have to determine
The perimeter and complete the sentences.
According to the question
1. The bottom side of the flag measures 5 feet because the triangle is an isosceles triangle.
2. Because SAS information is known the trigonometric triangle formula is used to calculate that the area is (5)(5)sin(36°) ≈ 7.35 square feet.
3. Recalling that this triangle is isosceles, we can write the area equation to solve for 7.35 = (x)(5)sin(72).
[tex]\rm 7.35 = \dfrac{1}{2}(x)(5)sin(72)[/tex]
4. Solving for x and adding this value to the length of the other sides, the perimeter.
[tex]\rm 7.35 = \dfrac{1}{2}(x)(5)sin(72)\\\\x =\dfrac{7.35 \times2 }{5 \times sin(72) }\\\\x = \dfrac{14.7}{5 \times 0.95}\\\\x = \dfrac{14.7 }{4.75}\\\\x =3[/tex]
Hence, the length of the other side of the perimeter is 3.
