Answer:
<em>Part 1 : Equation: ( 3x - 9 ) + 30 + 24 = 180,</em>
<em>Part 2 : Value of x ⇒ 45°,</em>
<em>Part 3 : Measure of Angle U ⇒ 126°</em>
Step-by-step explanation:
~ Part 1 ~
We know that ∑ of angles in a triangle is 180;
m∠ U + m∠ V + m∠ W = 180°,
<em>Equation: ( 3x - 9 ) + 30 + 24 = 180</em>
~ Part 2 ~
Now let us simplify the equation above to solve for x;
3x - 9 + 30 + 24 = 180,
3x - 9 = 126,
3x = 135,
x = 45 degrees ( ° ) ⇒
<em>Value of x ⇒ 45°</em>
~ Part 3 ~
If it is known that m∠ U ⇒ 3x - 9;
m∠ U = 3 * ( 45 ) - 9,
m∠ U = 135 - 9,
m∠ U = 126 degrees ( ° ) ⇒
<em>Measure of Angle U ⇒ 126°</em>
Answer:
D. two acute angles
Step-by-step explanation:
Let us quickly plot the vertices on a graph to obtain the figure in the attachment.
Connecting the four points gives a square.
We know a square has the following properties.
A. four right angles
.......True
B. four vertices
................True
C. two sets of parallel lines
......True
D. two acute angles...................False.....A square has four right angles.
Therefore the correct choice is D

Answer:
13.8–14.2 inches
Step-by-step explanation:
If you assume the "symmetrical and bell-shaped" distribution is a normal distribution, then 95% of observations will lie within 2 standard deviations of the mean:
... 14 in ±2×(0.1 in) = 13.8 in to 14.2 in
