Answer:
I only know B and C
Step-by-step explanation:
Part B)
2 (x+15) + 3x + 10+ 5x = 180 2x + 30 + 3x + 10 +5x = 180 10 +40 = 180
- 40 -40 10x divided by 10 = 140 divided by 10 x= 14
Part C)
A = 2 (x + 15) = 2 (14 + 15) = 2 * 29 = 58 degrees
< B = 3 x + 10 = 3 * 14 + 10 = 52 degrees
< C = 5 x = 5 * 14 = 70 degrees
When two chords of a circle intercept, the products of the segments are equal, that is, PT*QT=RT*ST
6*4=RT*10
RT=2.4
