Answer:
Step-by-step explanation:
take 60 degree as reference angle
using cos rule
cos 60=adjacent/hypotenuse
1/2=80/x(do cross multiplication)
80*2=x
160=x
Answer:
The sweater's original price is $105.
20% = 1/5
21 * 5 = 105
Answer:
Kindly check explanation
Step-by-step explanation:
Given the Equation :
(5/8)m = 25
The first step to take with this kind of equation is to multiply both sides by the denominator, 8
5m/8 * 8 = 25 *8
5m = 200
Then, we can divide both sides by 5 in other to isolate m
5m / 5 = 200 / 5
m = 40
The lateral area of a cone is 147ft².
The total surface area of the cylinder is 867ft².
The total surface area is 1014ft²
<h3>What is the lateral surface area of a cone?</h3>
The lateral area of a cone is defined as the area covered by the curved surface of the cone.
Lateral area of a cone = πr x √(r² + h²)
Where:
- r = radius = 12/2 = 6ft
- h = height = 5ft
- π = 3.14
3.14 x 6 x √(36 + 25) = 147ft²
<h3>What is the total surface area of the figure ?</h3>
Total surface area of the cylinder : πr(r + 2h),
(3.14 x 6) x (6 + 40) = 867ft²
Total surface area = 867 + 147= 1014ft²
