31 is the answer; this is because to get to the place-holder number “0” you have to add 19 to -19, then after this, you add 12, making the total 31.
Answer:
false
Step-by-step explanation:
Answer:
The triangles are not similar
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
<em>Triangle X.Y.Z</em>


---> angle X and angle Y are complementary angles
<em>Triangle H.G.J</em>
---> angle H and angle J are complementary angles


so
X.Y.Z is a
triangle
H.G.J is a
triangle
The measure of its corresponding angles are not congruent
therefore
The triangles are not similar
