Question

Find the measure of angle DAB from the given figure.

Answer 1

Answer:

angle DAB= 80

Step-by-step explanation:

as ABCD is quadrilateral therefore sum of all angle = 360

so here angle DAB = 90, BAD = 90

so therefore angle DAB + BAD + DCB + DAB = 360

90 + 90+ 100 + DAB = 360

280 + DAB = 360

DAB = 80

Answer 2

$\mathbb{ \ \ A\ N\ S\ W\ E\ R\: \: }$

DAB = 80°
