Question

the measure of three angle of a quadrilateral are 60 70 and 80 respectively then find the measure of fourth angle of the quadrilateral​

Answer 1

Step-by-step explanation:

60+70+80+x = 360

.....(all angles of quadrilateral)

x=360-210

x=150

Answer 2

Answer:

Fourth angle will be 150°

Step-by-step explanation:

Sum of all angles in a quadrilateral=360°

Let Fourth angle be X

X+60+70+80=360°

X=360-210

X=150°
