Answer: 33
Step-by-step explanation:
Angles inscribed in the same arc are congruent, so

-21/5 is the closest!!!
Hope this helps.
If you want me to explain why, just ask! :)
RT = RS + ST
8x - 43 = 2x - 4 + 4x - 1
8x - 43 = 6x - 5
8x - 6x = -5 + 43
2x = 38
x = 38/2
x = 19
QS = 2RS = 2(2x-4) = 2(2*19-4) = 2*34 = 68
You can use proportion
AB/BC = 3/2
DE/EF = 4/3
3/2 is not equal 4/3
so <span>the triangles are not similar</span>
The answer is 7x - 9 = 75. Please mark me brainiest
