sum of angles in a quadrilateral= 360

138+90+2x+x=360

228+3x=360

3x=360-228

3x=132

x=132/3

x=44

2x=44×2=88

hope it helps...

Answer 2

Answer:

x=16°

Step-by-step explanation:

By the angle sum property:

The sum of all the angles of a triangle is 180°

138°+90°+2x+x=180°

So.

228+3x=180°

228°-180°=3x

48°=3x

x=48°/3

x=16°
