Hi Gui, can you explain, the angles 20,35, 70 and 120 degrees.
Between AG and AF, I can see 20 and 70 degrees. That is not clear to me.
Hey guys!
I'm in need of some help again! :/ We're learning about tangents right now, I've got a test tomorrow morning. I've spent at least 5 hours in these 4 problems these past two days, and all I could figure out was 14 (55º).
Please help! Thanks in advance!
Hi Gui,
[12] Find m
This angle is formed by the intersection of secants AF and AG.
The measure of the angle is equal to the difference of the measures of the intercepted arcs.
[13] Find
This angle is formed by the tangent MH and chord MG.
The measure of the angle is equal to one-half the measure of its intercepted arc.
The intercepted arc here is .
You already know the measure of
You can find easily by subtracting arcs BC, CM, and FG from 180 since BG is a diameter.
Then add arcs FG and MF to get the intercepted arc you need. Then take half of it for your answer.
[14] Find m
This angle is formed by the intersection of two chords.
The measure of the angle is equal to one-half the sum of the measures of the intercepted arcs.
The intercepted arcs are CM and FG.
Your answer is incorrect.
[15] Find BE.
I don't see any segment measures at all in this figure. Therefore, BE cannot be determined.
