Question

three angles of a quadrilateral measures 680,740,and 1080 find the fourth angle​

Answer 1

Answer:

The fourth angle is 110°

Step-by-step explanation:

I will just assume the angles you have written are 68°, 74°, 108°.

Let's suppose the fourth angle is x

Sum of interior angles of a quadrilateral is 360. Then,

68 + 74 + 108 + x = 360

250 + x = 360

x = 360 - 250

x = 110
