If m _ RDC = 120°, then m DAC =
•60
•120
•240

Answer:
Option C.
Step-by-step explanation:
If a tangent and arc intersect at a point on a circle the measure of angle formed by the intersection will be half of the arc intercepted.
Therefore, m∠RDC =
Since m∠RDC = 120°
120 =
m(arcDAC) = 2×120°
m(arcDAC) = 240°
Option C. 240° is the answer.
Answer:
The measure of the arc DAC is 240°
Step-by-step explanation:
we know that
The semi-inscribed angle is half that of the arc it comprises.
so
m∠RDC=(1/2)[arc DAC]
we have
m∠RDC=120°
substitute
120°=(1/2)[arc DAC]
240°=[arc DAC]
Rewrite
arc DAC=240°

Answer:
x = 10
The second number is 50
Step-by-step explanation:
Givens
The first number = x
The second number = 5x
Together when added the answer is 60
Equation
x + 5x = 60 Combine like terms
Solution
6x = 60 Divide by 6
6x/6 = 60/6
x = 10
