Consider circle h with a 6 centimeter radius. if the length of minor arc st is 11/12 π, what is the measure of ∠rst? assume rs ≅ ts.
a) 15°
b) 25°
c) 30°
d) 45°

The measure of ∠RST=15°

A is correct.

Step-by-step explanation:

Given: Circle with centre H. Radius of circle is 6 cm.

Length of minor arc

RS ≅ TS   (Given)

arc RS = arc ST ( equal choed subtended equal arc.

Major arc RT

Minor arc RT

Central angle of minor arc = ∠RHT

Therefore,

Now we will change radian to degree

Hence, The measure of ∠RST=15°

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
