To prove the triangles congruent using the SSS (side-side-side) postulate, you would need to know that d. HL=LM. You know that two of the sides are congruent, so this last side will satisfy the the postulate.
A b c and d r not answers, u need to tell how the different variations would change based on the numbers and where they r
Answer:
angle Z=20°
side xy≈15.36
hypotenuse≈19.49
Step-by-step explanation:
Find angle z adding the other two angles and subtracting that by 180 to get 20.
(12)tan(20) gets you side xy which is 15.36
12^2+15.36^2=xz^2
Answer:

Step-by-step explanation:
To add fractions <em>with the same denominator</em>, simply add the numerators:

So:
