1 answer:
Segments BA and CA are drawn perpendicular to two chords. The segments are congruent, so that makes the two chords congruent (they are the same distance from the center of the circle). So segments GF and HE are congruent.
In the second problem, it helps to ignore the pieces of information you don't need. Angle GET is formed by two secants, IE and NE. I've attached a diagram that shows the angle you're trying to find and its TWO intercepted arcs. A fact about circles is that if the angle is formed by two secants (their intersection is outside the circle), the measure of the angle is half the DIFFERENCE of the measures of the intercepted arcs.
The measure of angle GET = 1/2 (74 - 18) = 1/2(56) = 28 degrees.

Answer:
12<u> = </u>7<u> + </u>2<u> + </u>3
Step-by-step explanation:
Given:
Number of games played last week = 12
Number of games played on Monday this week = 7
Number of games played on Wednesday this week = 2
Also given:
James and Amy play 3 more games.
So Number of games played more = 3
We need to fill in the blanks 12 __ 7__2__3 with signs '+', '-','='.
Solution:
It is given that they have played the same number of games as last week.
So we can say that;
Number of games played last week is equal to Number of games played on Monday this week plus Number of games played on Wednesday this week plus Number of games played more.
framing in equation form we get;
Hence we have fill the blanks as 12<u> = </u>7<u> + </u>2<u> + </u>3.
