Two parallel lines are crossed by a transversal. Parallel lines x and y are cut by transversal w. On line x where it intersects
Tems11 [23]

Answer: The size of angle 1 is 56.5°

Step-by-step explanation: Please refer to the diagram attached.

The question gives us two parallel lines x and y as shown in the attachment. Then both parallel lines are cut by a transversal line w.

The transversal eventually results in four angle being formed at each point of intersection, both in line x and in line y. In line x, the angles formed are given as angles, 2, 4, 3 and 1. In line y, the angles formed are 6, 8, 7 and 5.

It is important to note that with the inclusion of the transversal line w, there is a relationship between the angles. looking at line y, we have one of the angles measuring 123.5 degrees (angle 6). That means angle 8 is derived as follows;

Angle 8 + Angle 6 = 180 (Angles on a straight line equals 180)

Angle 8 + 123.5 = 180

Subtract 123.5 from both sides of the equation

Angle 8 = 56.5 degrees

Note also that angle 5 is opposite angle 8 and opposite angles are equal. Therefore angle 5 equals 56.5 degrees as well.

Looking at line x, angle 1 is alternate to angle 8 (alternate interior angles are equal), therefore angle 1 equals 56.5 degrees also.

The diagram and the accompanying explanation shows that angle 1 measures 56.5°

Question 1(Multiple Choice Worth 5 points)
Ket [755]
Well, to cover the whole bridge, is 6/6, or 1 whole

so hmmm   \bf \begin{array}{ccllll}
concrete&bridge\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
\frac{4}{5}&\frac{5}{6}\\\\
x&\frac{6}{6}
\end{array}\implies \cfrac{\frac{4}{5}}{x}=\cfrac{\frac{5}{6}}{\frac{6}{6}}\implies \cfrac{\frac{4}{5}}{\frac{x}{1}}=\cfrac{\frac{5}{6}}{\frac{6}{6}}

\bf \cfrac{4}{5}\cdot \cfrac{1}{x}=\cfrac{5}{6}\cdot \cfrac{6}{6}\implies \cfrac{4}{5x}=\cfrac{5}{6}\implies 4\cdot 6=5\cdot 5x\implies 24=25x
\\\\\\
\boxed{\cfrac{24}{25}}=x

Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who
alekssr [168]

Answer:

They traveling at 0.37\ m/s in backward direction.

Step-by-step explanation:

Given mass of Ammy m_1=55kg

and velocity is forward at v_1=3m/s

Also, mass of Jenny m_2=40kg

Who is travelling in opposite direction v_2=-5m/s

Let velocity in forward direction is positive and velocity in backward direction is negative.

Also, velocity after crash is v

As they crashed into each other and they moved as one mass. We can apply principle of conservation of momentum.

Conservation of momentum says momentum before collision should equal to momentum after collision.

m_1v_1+m_2v_2=(m_1+m_2)v

(55\times3)+(40\times(-5))=(55+40)v\\\\165-200=95v\\\\-35=95v\\\\v=\frac{-35}{95}=-0.368m/s

So, velocity after collision v≅-0.37m/s is in opposite direction. That is the direction of Jenny.
