Answer:

Smaller value - 30; Larger value - 150

Step-by-step explanation:

This is shown on a Radian Circle.

To prove that this is true sin(30) = 1/2 & sin(150) = 1/2

Answer: the smaller value of θ is 30° and the larger value of θ is 150°.

Step-by-step explanation:

We know, for the notable angles and values of the trigonometric functions (you can find a lot of tables of it) that sin(30°) = 1/2 and also that sin(150°) = 1/2

Then if 0°<θ<180°, the smallest value of θ is 30°, and the biggest value is 150°

You also can use the inverse function

if sinθ= 1/2

then θ= asin(1/2)

$To \; find \; the \; maximum \; number \; of \; items \; possible \; in each \; packet,\\we \; need \; to \; find \; the \; Greatest \; Common \; Factor\\ \; of \; 527 \; Pencils, \; 646 \; erasers \; and \; 748 \; sharpeners.\\\\We \; need \; to \; list \; the \; Factors \; of \; each \; number \; as \; given \; below\\ \; and \; identify \; the \; greatest \; common \; factor.$

$The \; factors \; of \; 527 \; are:\\1, \; 17, \; 31, \; 527\\\\The \; factors \; of \; 646 \; are:\\1, \; 2, \; 17, \; 19, \; 34, \; 38, \; 323, \; 646\\\\The \; factors \; of \; 748 \; are:\\1, \; 2, \; 4, \; 11, \; 17, \; 22, \; 34, \; 44, \; 68, \; 187, \; 374, \; 748\\\\Then \; the \; greatest \; common \; factor \; is \; 17.$
