Attach an image of the two triangles on a cartesian plane
Answer:
x=2
Step-by-step explanation:
9x+11=29
9x=29-11
9x=18
x=2
Step-by-step explanation:
So the Ap will be x,x+10,x+20,x+30
Sum of the angles of a quadrilateral is 360
x+x+10+x+20+x+30=360
4x+60=360
4x=300
x=75
So the angles are 75,85,95,105
5, 5/2, 2.71, 2 3/4
hope this helps
