Given:SW is diameter of circleR m\overarc ST = 30\degree Prove: RTW = 15\degree
1 answer:
Check the picture below.
we know that the arcST is 30°, meaning the inscribed angle intercepting it will be half that or 15°.
in the triangle RWT, two sides of it are RT and RW, both of which are radius segments and thus equal, meaning that triangle RWT is an isosceles, and in an isosceles the twin sides also make twin angles, meaning that ∡RTW is a twin of the inscribed angle ∡RWT.

Answer:
The inequality that represents p are p 125 or p
85.
Step-by-step explanation:
We are given that in order to be invited to tutoring or extension activities, a student's performance must be at least 20 points higher or lower than an average score. The average score is 105.
Let p = the scores for students who are eligible for tutoring or extension activities.
<u>The first condition</u> states that a student's performance must be at least 20 points higher than an average score, that means;
p (105 + 20)
p 125
Similarly, <u>the second condition</u> states that a student's performance must be at least 20 points lower than an average score, that means;
p (105 - 20)
p 85
So, the inequality that represents p are p 125 or p
85.
