Answer:
∠A = 20°
Step-by-step explanation:
Given:
Line AB equal to line AC
So, we can say that;
∠B = ∠C
So
∠B = ∠C = 80°
Using angle sum rule
∠A + ∠B + ∠C = 180°
∠A + 80° + 80° = 180°
∠A = 20°
Answer:
Resultant force = 70.71067811865 pounds
Step-by-step explanation:
Pythagoras theorem is used to calculate the resultant force since the angles between two wires is 90⁰
Resultant force² = 50² + 50² = 5000
Resultant force = (5000)¹/² = 70.71067811865 pounds
Answer:
inverse variation
Step-by-step explanation:
direct variation
y =xk
inverse variation
xy =k
Lets see if the data fits either
(4,25) and (5,20) and (10,10) are three points
direct variation
y/x = k which is a constant
10/10=1 does not equal 20/5=4 so it cannot be direct variation
inverse variation
xy =k
4*25 =100 5*20 =100 10*10 =100
This is a constant so it is inverse varaiton
It is given in the question that
A new youth sports center is being built in oak valley. The perimeter of the rectangular playing field is 522 yards. The length of the field is 4 yards less than quadruple the width.
Let the width be x yards . And the length is 4 yards less than 4times the width .
So length is
And the perimeter is the sum of all sides, that is
Combining the like terms,
Adding 8 to both sides
Therefore the width is 53 yards, and length is 4 less than 4 times the width, that is
(3,2) is the center and the radius is 2. You can see this by taking where the dot is in the graph (in this case (3,2)) that is your middle, while the radius is one half of the circle, basically how many points are between the circle and the dot. Hope this helps!
