Answer:
Option C.
Step-by-step explanation:
Given: In 
.
In 
,
(Angle sum property)
Now,
In a triangle, the greatest angle has largest opposite side and smallest angle has smallest opposite side. So, we conclude that
Therefore, the correct option is C.
Answer:
let the two numbers are x & y
x+y=30...eq(1) &x-y=12....eq(2)
x=30-y then put in the eq(2)
30-y-y=12
30-2y=12
-2y=12-30
-2y= -18
y=9 then we put this answer in to eq(1)
so,x+y=30
x+9=30
x=30-9
x=21
so, the two numbers are (21,9)
Answer:
The circumference formula for a circle is C=πd where C is the circumference, d is the diameter of the circle and π is a constant. If you plug in 6 for C and solve the equation for d like:
6= πd and then divide both sides of the equation by π you get that d = 1.90
To find the central angle of an arc you would use the equation S = rθ where S is the length of the arc, r is the radius of the circle, and θ is the measure of the angle which in this case is unknown. So with S = 1 and r = d/2 = 1.90/2 = 0.9549 you would have an equation that looks like this:
1 = 0.9549θ.
If you divide both sides of the equation by 0.9549 you get θ = 1.047197 radians.
The question asked for the angle measure in degrees so you would need to convert the angle measure to degrees by multiplying the degree measurement by 180/π
