Answer:
Step-by-step explanation:
(Add similar elements)
(2-2=0)
( Divide both sides by 72)
Now,
m∠km:-
(Multiply 19*5= 95)
(Subtract)
Therefore, m∠km=93° is the answer.

Answer:
25.33 is the circumference of the circle
Step-by-step explanation:
Here, given the measure of the arc, we want to get the circumference of the circle
mathematically, the length of an arc can be calculated using the formula;
theta/360 * 2 * pi* r
where 2 * pi * r = circumference of the circle
theta is the angle subtended at the center which is 55 degrees in this case
Thus, we have ;
55/360 * 2 * pi * r = 3.87
2 * pi * r = (3.87 * 360)/55
2 * pi * r = 25.33 inches

Answer:
60%
Step-by-step explanation:
We need convert 3/5 into a percent in order to find the answer.
We can convert by first dividing 3 by 5 to find the decimal value.
3/5= .6
Now we need to multiply by 100 to make it a percentage
.6 x 100= 60
60%
Answer:
(2, 1 )
Step-by-step explanation:
Using the Section formula
For endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n
Then coordinates of point are
[ , ]
Here m = 5, n = 2, (x₁, y₁ ) = (- 3, - 9), (x₂, y₂ ) = (4, 5), thus partitioned point
= [ , ]
= [ , ]
= ( , )
= (2, 1 )
