Question

If three angles of a quadrilateral are 120°, 45° and 70°. Find the
fourth angle​

Answer 1

Answer:

In a Quadrilateral, sum of all angles= 360

→ 120 + 45 + 70 + x = 360

→ x = 125

The fourth angle is 125

Answer 2

Answer:

$\huge \bold\red{Answer}$

the sum of interior angles in quadrilateral =360°

the measure of three angels are:-

• 120°
• 45°
• 70°

now,let the 4th angle be x

so,120+45+70+x=360

so,235+x=360

x=360-235

x=125

hope this helps.!!
