Question

Three interior angles of a quadrilateral have measures of 111°, 134°, and 69º. Whats the fourth angle measure?

Answer 1

Answer:

Step-by-step explanation:

sum of for angles of a quadrilateral=360

111+134+69+x=360

314+x=360

x=360-314=46

fourth angle=46°

Answer 2

All angles of a quadrilateral add up to 360 degrees, so 111+134+69+x=360

Solving it we get:

314+x=360
x=46 degrees.

I hope this helps!
