Are the two triangles below similar?
2 answers:
Answer with explanation:
⇒Information about ΔSTU
∠S=28°
∠T=70°
Third Angle using Angle sum property of Triangle
∠U=180°-70°-28°
=82°
ST=8 units
⇒Description of Δ VWX
∠W=70°
∠X=92°
Third Angle using Angle sum property of Triangle
∠U=180°-70°-92°
=18°
WX=4 units
VX=10 Units
Now, In ΔSTU and Δ VWX
The corresponding Angles of two triangles are not equal.And, the description about corresponding sides are not equal.
Option D
No; they do not have congruent corresponding angles.

Answer:
a) Sample mean: 48.71
Sample median: 48.3
Sample variance: 5.41
Sample standard deviation: 2.37
Step-by-step explanation:
a) Sample mean:
Sample median: M=48.3
Note: I order the data increasingly and take the value N / 2 = 40. In this way there are 39 values above and 39 values below the median.
Sample variance:
