Help? New question for GEOMETRY Sarla made a drawing of a geometric figure for a fabric print. The figure was a quadrilateral with a pair of angles measuring 60° each. If the figure she drew is a concave polygon, which of these could be the measures of the other two angles? 45°, 235° 15°, 225° 110°, 130° 140°, 110°
convex - all angles less than 180 sum of angles?
what?
360-sum of angles
i do you get the sum of angles?
de answer is 110 nd 130
thanks
:).. nytime
hey wait did u say concave?
yes
den de ans wud b 15 nd 225
concav will hav an internal angle gr8r dan 180
let the two unknown angles be 'x' & 'y'. then the equation will be 360-(x+y)
@jiteshmeghwal9 ...bt der wud b two ans if v do it lyk de way u said...notice de pint dat de figure is concave...so e ans is 225 nd 15
but u don't know that the angles are equal or nt
itz given dat de figure is quadrilateral which means de sum of de angle measures is 360 agreed?
den as de figure is concave, one of de internal anglz should b gr8r dan 180....so only 2 choices r left, eithr 45°, 235° or15°, 225° ...nd if v add all anglez up (givn two angles r 60 each) v get 360 only fr 15+225+60+60...de odrz wud exceed 360
