Pretty sure it’s d) counterclockwise rotation 90 degrees
Answer:
They are both right becuase if you just take away 1 from 20 and 10 you get 2 and 1. For the 4:2 one take away 1 and mutiply by 2 equalling 4:2 but they are still the same thing.
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
expected over total
14/14+7 = 14/21 = 2/3
Answer:
The answer to your question is 31.4°
Step-by-step explanation:
Data
SR = 54 cm
SQ = 99 cm
RQ = 141 cm
∠QRS = ?
Process
1.- Use the law of cosines to find ∠QRS
cos QRS = (SQ² - RS² - RQ²) / -2(SR)(RQ)
-Substitution
cos QRS = (99² - 54² - 141²) / -2(54)(141)
-Simplification
cos QRS = (9801 - 2916 - 19881) / -15228
cos QRS = -12996 / -15228
cos QRS = 0.85343
2.- Find QRS
∠QRS = 31.4°
Option( d ) is the correct one.
