Question

Q8 - find the measure of angle QPR.

Answer 1

Answer:

35°+angleP+angleQ+angleR=360°

35+90+90+angleP=360

angleP= 360-180-35

angleP=145

hope it helps....

Answer 2

Answer:

Step-by-step explanation:

A BISECTOR DRAWN CONNECTING POINTS B AND P CUTS THE 35 DEGREE INTO TWO EQUAL HALVES EACH OF 17.5 DEGREE .

THIS RESULTS IN THE FORMATION OF TWO RIGHT ANGELED TRIANGLE

SINCE THE TOTAL ANGLE OF A TRIANGLE IS 180 DEGREE.

IN TRIANGLE BOP

<BOP+<OPB+<PBO  = 180

90+<OPB+17.5= 180

107.5+<OPB = 180

<OPB = 72.5

IN TRIANGLE BPR ALSO

<BPR = 72.5

THERFORE:

<OPR= <OPB+<BPR

         = 72.52+72.5

         = 145 DEGREES.

HOPE THIS HELPS.
