The triangles are similar by AAA so make ratios and solve
A right triangle is a triangle that consist of an angle which one angle is 90degree and the remaining angle would be less than to 90 and the best answer to your question based on my calculation i think the answer is A.
Let the number be x.
7x-x=42
6x=42
x=7
the number is 7
