Question

130 degrees, 80 degrees. Measures of three angles in a quadrilateral are 70 degree,

Answer 1

Answer:

There is nothing to answer. It is 70 degrees

Step-by-step explanation:

Let the angles be x and x

therefore

x+x+130+70=360

2x+200=360

2x=160

x=160/2

=80° is the measure of each angle

Answer 2

Step-by-step explanation:

Let the fourth angle be x ,

By angle sum property of quadilaterals

130+80+70+x = 360

280+x=360

Hence x = 80°

Therefore the four angles are 80°, 80°,130°and 70°

Hope this helps
