1 answer:
To solve your question, you add all of the measurements together, set them equal to 180, solve for x, and plug x back in for whichever angle they are asking for; in this case, they want angle R 7x + 12x + 20 + 20x - 35 = 180 39x - 15 = 180 39x = 180 + 15 39x = 195 x = 5 Angle R = 12x + 20 12(5) + 20 60 + 20 80Option C is your answer.

answer below
Step-by-step explanation:
∠3 = 76°
∠1 = ∠3 = 76° (vertical angle)
∠2 = 180 - ∠1 = 180° - 76° = 104° (supplementary adjacent angle)
∠4 = ∠2 = 104° (vertical angle)
-2 | 8-x| - 6 = -12...add 6 to both sides -2 |8-x| = -12 + 6 -2 |8-x| = - 6...divide both sides by -2 |8-x| = -6/-2 |8-x| = 3 8 - x = -3 -(8 - x) = -3 -x = -3-8 -8 + x = -3 -x = -11 x = -3 + 8 x = 11 x = 5 not correct.....sign error
Answer:
∡TQS = 10x -3
Step-by-step explanation:
∡TQS = ∡RQS - ∡RQT
= 22x - 11 - (12x - 8)
= 10x -3
