In the diagram, PR is a diameter of the circle RSP, RP is produced to T and TS is a tangent to the circle at S. If < PRS = 24\(^o\), calculate the value of < STR

A.

24\(^o\)

B.

42\(^o\)

C.

48\(^o\)

D.

66\(^o\)

Correct answer is A

RSP = 90 < substance in semi a circle

RPS = 180 - (90 + 24)

= 180 - (114)

= 66

TPS = 180 - 66

= 114

RST = 24

< STR = 180 - (114 + 24)

= 180 - 138

= 42\(^o\)

Find the value of m in the diagram

A.

72\(^o\)

B.

68\(^o\)

C.

44\(^o\)

D.

34\(^o\)

Correct answer is C

2x + m = 180

x + m = 112

x = 122 - m

2(112 - m) + m = 180

224 - 2m + m = 180

224 - m = 180

224 - 180 = m

m = 44\(^o\)
