The answer is C: Divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
Explanation.
Let r = radius of the circle
Then the circumference is C = 2πr.
Let the degree measure of the arc be x degrees.
In radians, the angle is (x/180)π radians
The measure of the arc is
r*(x/180)π = (x/180)*πr
= (2x/360)*πr
= (x360)*2πr
= (x/360)*C
This proves the statement for the answer because
x/360 is the degree measure divided by 360,
C is the circumference.

Answer:
d = 5
Step-by-step explanation:
-7d = -35
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, d. Divide - 7 from both sides:
(-7d)/-7 = (-35)/-7
d = -35/-7
d = 35/7
d = 5
d = 5 is your answer.

Let x be the base of the triangle, and
2x + 4 be the height.
One of the ways in solving for the area of a triangle is to half the product of its height (h) and base (b). Mathematically,
A = bh / 2
Substituting the expression for b and h and the given condition for the area,
<em>(x)(2x + 4) / 2 ≤ 168</em>
