The model shows 7/10 which is equivalent to 70/100 (multiply top and bottom by 10).
Answer:
its upside down
Step-by-step explanation:
Angle SQN = 66 degrees (given)
----------------------------
Use the inscribed angle theorem to get
Minor Arc SN = 2*(angle SQN)
Minor Arc SN = 2*(66)
Minor Arc SN = 132 degrees
----------------------------
Arc PSN is a semicircle so it is 180 degrees, meaning that...
Arc PSN = (minor arc PS) + (minor arc SN)
180 degrees = (minor arc PS) + (132 degrees)
180 = (minor arc PS) + 132
180 - 132 = (minor arc PS) + 132 - 132
48 = minor arc PS
minor arc PS = 48 degrees
central angle RTP = minor arc PS = 48 degrees
----------------------------
Focus on triangle PTR; isolate angle PRT
(angle TPR) + (angle PRT) + (angle RTP) = 180
(90) + (angle PRT) + (48) = 180
(90+48) + (angle PRT) = 180
138 + (angle PRT) = 180
138 + (angle PRT) - 138 = 180 - 138
angle PRT = 42 degrees
----------------------------
----------------------------
Final Answer:
The measure of angle PRT is 42 degrees
Y = sin(4x + 3)
4x + 3 = arcsin y
4x = arcsin y - 3
x = (arcsin y - 3)/4
Inverse => f^-1(x) = (arcsin(x) - 3)/4
