Answer:
Step-by-step explanation:
We can use pytho theorem to find X because its a right triangle, so:
a^2 + b^2 = c^2
plug our numbers
1^2 + 1^2 = x^2
simplify
1+1 = x^2
2=x^2
answer = root2
Answer: D
multiply the denominators then the numerators
what
name as AB =CD
angle A=angle D
BC=BC
hence angle ABC is congruent to angle BCD
(by sas congruency)
hence proved
