It is impossible to solve for both variables without a second equation.
Answer:
x = 10
Step-by-step explanation:
The arc size (100) is the same size as the central angle (<AOC)
The angle labeled 5x is 1/2 of the central angle.
Since the central angle = 100o the 5x angle = 50 degrees.
5x = 50 Divide by 5
5x/5 = 50/5
x = 10
Answer:
Solving for Area of Circle is usually the easiest for me. The answer is 530.66 cm squared.
Step-by-step explanation:
We know that the formula for solving the area of a circle is A = pi radius squared.
Substitute the radius, (in this case is 13), into the formula.
A = pi radius squared.
A = 13 squared pi
Then, do 13 times 13, since 13 is being squared.
13 times 13 = 169
A = 169 pi
Then we know that we are using 3.14 for pi. Multiply 169 to 3.14
A = 169 times 3.14
A = 530.66
Hope this helps. Sorry if I was wrong.
