help me solve please!

Answer:
x=10, m<ACD=25
Step-by-step explanation:
To find x you know that it has to equal 19 since the figure is a rhombus and because there are lines marking the congruence. You do 2x-1=19 and get 2x=20 which is 10.
For m<ACD you know m<CDA is 130 because opposite angels are congruent. That means that the rest of the two angles have to equal 50 and since they're equal(from base angles theorem) it would be 25.
