Question

in a parallelogram abcd if <b=45 what is the measure of <c

Answer 1

the following figure is a parellalogram

in a parellalogram, adjacent angles are supplementary , meaning the add up to 180°

therefore,
let the other angle be x

45°+x=180°
x=180°-45°
x=135°

other angle is 135°

Answer 2

hi frnd

in parallelogràm sum of 2 adjacent angles is 180

so here

one of the adjacent angle = 45

let ,, other to be X


so,, here

45 + X = 180

X = 180 -45

X = 135


here X = <c

<c = 135
