Question

f three angles of a quadriatiol are 100 degree,80digree and 70 degree,what is the mesure of the fourth degree

Answer 1

Answer:

BY A.S.P. OF QUADRILATERAL, WE CAN SAY THAT ALL THE ANGLES ARE EQUAL TO 360 DEGREE.

SO, 100+80+70+X=360

      250+X=360

      X=360-250

      X=110

Answer 2

$\huge\underline{Question}$

The three angles of a quadrilateral are 100 degree, 80 degree and 70 degree, what is the measure of the fourth degree ?

$\huge\underline{Solution}$

1st angle = 100°

2nd angle = 80°

3rd angle = 70°

$\underline{According \: to \: question}$

=> 100° + 80° + 70° + 4th angle = 360°

=> 250° + 4th angle = 360°

=> 4th angle = 360 - 250

=> 4th angle = 110°

So, the measure of 4th angle is 110°. (Ans)
