Answer:
Option B. AA
Step-by-step explanation:
we know that
Angle-Angle (AA) Similarity Postulate, states that If two angles of one triangle are congruent to two angles of another, then the triangles must be similar
In this problem
<em>In the triangle XYZ</em>
∠X=70°
∠Y=90°
∠Z=90°-70°=20° (remember that angle X and angle Z are complementary)
<em>In the triangle UWV</em>
∠V=20°
∠W=90°
∠U=90°-20°=70° (remember that angle V and angle U are complementary)
therefore
Traingles XYZ and UWV are similar by AA Similarity Postulate
Answer:
1. Figure C has reflection symmetry.
2. A and D have reflection symmetry.
Step-by-step explanation:
1. When you cut the arrow horizontally, you get the same shape on each side.
2. When you divide them, you should have symmetry, meaning they are the same when divided/cut.
B. 11.33 is closer to the area of a circle with a radius of 2.1
Answer:
Hey there!
Density = Mass/Volume
Mass= 6g
Volume=24 mL, which is 24 cm^3
Density= 6g/24 cm^3
Density=0.25 g/cm^3
Let me know if this helps :)
Step-by-step explanation:
3(12)=2(y-1)
36=2y-2
36+2=2y
38=2y(<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>two</em><em>)</em>
y=19
