In the figure, PQ||ST, RS||UV. If PQR = 35^o and QRS = 65^o, find STV

30^o

35^o

55^o

65^o

View answer & explanation

Correct answer is A

Draw XW//PQ and ARW = 35^o (alternative angle)

WRS = 60 - 30

= 30^o

RSR = 30^o (Alternative angle)

STV = 30^o (Alternative angle)

In the figure, \(\bigtriangleup\)PQT is isosceles. PQ = QT, SRQ = 35^o, TPQ = 20^o and PQR is a straight line.Calculate TSR

20^o

55^o

75^o

140^o

View answer & explanation

Correct answer is C

Given \(\bigtriangleup\) isosceles PQ = QT, SRQ = 35^o

TPQ = 20^o

PQR = is a straight line

Since PQ = QT, angle P = angle T = 20^o

Angle PQR = 180^o - (20 + 20) = 140^o

TQR = 180^o - 140^o = 40^o < on a straight line

QSR = 180^o - (40 + 35)^o = 105^o

TSR = 180^o - 105^o

= 75^o

In the figure, PQRS is a circle. If chords QR and RS are equal, calculate the value of x

80^o

60^o

45^o

40^o

View answer & explanation

Correct answer is D

SRT is a straight line, where QRT = 120

SRQ = 180o - 120o = 60o - (angle on a straight line)

also angle QRS = 180o - 100o (angle on a straight line) . In angles where QR = SR and angle SRQ = 60o

x = 100 - 60 = 40o
