Sagot :
Answer:
arcPSU = 224degrees
Step-by-step explanation:
From the given diagram;
arcPSU = arcPQ + arcQR + arcRS + arcST + arcTU
Given
arcPQ = arcTU
arcQR = arcRS = 37
arcAST = 90
Since 136 + arcPQ + 37+37+90+arcTU = 360
136+2arcPQ+ 37+37+90= 360
2arcPQ+300 = 360
2arcPQ = 360 - 300
2arcPQ = 60
arcPQ = 60/2
arcPQ = 30degrees
Substitute into the above expression
arcPSU = arcPQ + arcQR + arcRS + arcST + arcTU
arcPSU = 360 - arcPU
arcPSU = 360 - 136
arcPSU = 224degrees
