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:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
