Three parallelograms are hinged at each vertex to create an arm that can extend and collapse for an exploratory spaceship robot. What is m<1?
Given:
Three parallelograms are hinged at each vertex.
To find:
The measure of angle 1.
Solution:
From the given figure it is clear that angle on the vertex = 122°.
Now let angle 2 be the vertex angle in second parallelogram as shown in below figure.
[tex]m\angle 2=122^\circ[/tex] (Vertically opposite angles)
Two consecutive angles of a parallelogram are supplementary angles.
[tex]m\angle 1+m\angle 2=180^\circ[/tex]
[tex]m\angle 1+122^\circ=180^\circ[/tex]
[tex]m\angle 1=180^\circ-122^\circ[/tex]
[tex]m\angle 1=58^\circ[/tex]
Therefore, the measure of angle 1 is 58°.

Positive numbers must have the positive sign (+) in front of them.
True False
Answer:
False
Step-by-step explanation:
If a number has no sign, it usually means that it is a positive number. Any numbers greater than zero are described as positive numbers. Usually, we don’t put a plus sign in front of positive numbers because the general understanding is that numbers without a sign are positive.

Please help me I have no clue what to do
Answer:
D
Step-by-step explanation:
The interquartile range IQR = Q₃ - Q₁ = 13. The most commonly accepted definition of an outlier is any value greater than Q₃ + 1.5 (IQR) = 110.5 or less than Q₁ - 1.5 (IQR) = 58.5. Looking at the minimum and maximum values, we see that there are no outliers on the lower end, and at least one outlier on the upper end.

Westmoreland, CA is 157 feet below sea level. Dallas, TX is 430 feet ABOVE sea level. What is the distance between the two cities?
West Moreland is -157 ( below sea level would be a negative value)
Dallas is 430 above
-157 to sea level is 157 feet
Sea level to 430 is 430 feet
Total distance = 157 + 430 = 587 feet.
Answer:
587 feet
Westmoreland is 157 feet below the sea level.
This is a negative number, so add 157 to get to 0.
Dallas is 430 above sea level.
Add 430 and 157. You get 587.
Hope it helps!

My notes for rhombuses are: All sides are congruent. Diagonals are perpendicular. Diagonals are angle bisectors.
Answer:
∠BAC = 122°
Step-by-step explanation:
From your notes, you know that ...
∠APB = 90°
12y° = 90°
y = 90/12 = 7.5
Then angle ACP is ...
∠ACP = (4y -1)° = (4(7.5) -1)° = 29°
Angle BAC is the ape.x angle of isosceles triangle BAC, whose base angles are 29°. Hence, ...
∠BAC = 180° -2(29°)
∠BAC = 122°
