FIND ANGLE PTQ ANGLE QTU ANGLE SUT ANGLE RUQ ANGLE RQU ANGLE UQT
​

Answer 1

in ∆TPQ

ANGLE P =90°

angle Q=20

angle P+angleQ+anglePTQ=180° ( angle sum property )

90+20+angle PTQ=180°

110+angle PTQ =180

angle PTQ =180-110

angle PTQ =70

in ∆UST

angle S=90

angle T=45

angle S+ angle T+angle SUT= 180. ( angle sum property )

90+45+angle SUT=180

135+angle SUT =180

angle SUT= 180-135

angle SUT=65

in line SR

angle SUT=65

angle TUQ=70

angle SUT + angle TUQ =135

135+ angleRUQ= 180. ( linear pair )

angle RUQ =180-135

angle RUQ=65

in ∆ QRU

angle R=90

angle RUQ=65

angle R+angleRUQ+angle RQU=180. ( angle sum property )

90+65+angle RQU=180

155 + angle RQU=180

angle RQU=180-155

angle RQU=25

in angle Q

anglePQT+angleRQU+angleUQT=90. (side of a square)

20+25+angleUQT=90

45+angleUQT=90

angleUQT=90-45

angleUQT=45

in∆UTQ

angle UQT =45

angle RUQ =70

angle UQT+angle RUQ+angle UTQ=180. ( angle sum property )

45+70+angleUTQ=180

115+angleUTQ=180

angleUTQ=180-115

angleUTQ=65
