The angle m∠ABC is 70 degrees.
<h3>How to find angle in a rhombus?</h3>
The angle in a rhombus can be found as follows;
The opposite angle of a rhombus are congruent.
Therefore,
∠B = 140 degrees
Hence, the diagonal of a rhombus bisect an angle.
Therefore,
m∠ABC = 140 / 2
m∠ABC = 70 degrees.

In the given figure we have two similar triangles:
a) Triangle ABC
b) Triangle ADE
Two sides of triangle ABC are 2 and x
The two corresponding sides of triangle ADE are (2+1)=3 and 1
The ratio of corresponding sides of similar triangles is always equal, so we can write:
Therefore, the measure of x will be 2/3
Answer:
X= 27 2x27=54+15=69 111+69=180
