Answer:
30°
Step-by-step explanation:
First we must know that the sum of the interior angles of a triangle sum up to 180°. Furthermore, a straight line is also 180°. By using these what we know we can determine what the value of m∠X is.
First we know that m∠W and m∠Z make up a straight line, since m∠W is 105° it follows that:
180° = m∠W + m∠Z
And so:
m∠Z = 180° - m∠W = 180°-105° = 75°
m∠Z = 75°
Now, we also know that the sum of m∠X + m∠Y + m∠Z = 180° and so:
m∠X = 180° - m∠Y - m∠Z
m∠X = 180° - 75° - 75° = 30°
Therefore, m∠X = 30°

Answer:
512 cm^3
Step-by-step explanation:
The side length is 8 cm
V = s^3 where s is the side length
V = 8^3
=512 cm^3
Answer:
∠1=128°
∠2=52°
∠3=47°
∠4=133°
∠5=81°
Step-by-step explanation:
6.
∠1=180-52=128°
∠2=52°(alternate angles)
∠4=180-47=133°
∠3=47°(alternate angles)
∠2+∠3+∠5=180
52+47+∠5=180
∠5=180-99=81°
