I think it’s C because a triangle is 180 degrees and it’s a right triangle which means there is a 90 degrees angle + 30 degrees.
90+30=120. 180-120=60
Which means the third angle is 60 degrees
It would be 3/19. Cause you add all and that would be denom.
Answer:
20078/243
Step-by-step explanation:
sn = a1-a1r^n/1-r
sn = a1 * 1-r^n/1-r
s7 = 6 * 1 - (-5/3)^7/1-(-5/3)
s7 = 6 * 10039/729
s7 = 6 * 10039/243*3
s7 = 2 * 10039/243
s7 = 20078/243
