1. The structure of the supports for the hill consists of steel beams that
Darina [25.2K]

a) Parallel for both line segments have the same slope = -5/4

b)  55º

Step-by-step explanation:

a) To verify the parallelism of these line segments, It's necessary to find the slope of each one. Parallel lines share the same slope value:

m_{BC}=\frac{0-150}{120-0}=-\frac{-5}{4}\\m_{AD}=\frac{0-125}{100-0}=-\frac{5}{4}

b) If ∠DAB = 125°, what is the measure of ∠CBA? Justify your reasoning.

Those beams do not form a parallelogram because:

Using the formula of distance between those points

d=\sqrt{(y_{2}-y_1)^{2}-(x_{2}-x_{1})^2  

\overline {AB}=25\: \: \: \overline{CD}=20\: \: \overline{AD}=160 \: \: \overline{BC}=192

So this is a trapezoid.  And two adjacent angles within a trapezoid are supplementary, so If ∠DAB = 125º then 180 - ∠CBA=55º

What % of 60 is 35?
STatiana [176]

Answer:

58.33%

Step-by-step explanation:

  is            %

--------  =  ---------

  of           100

Just plug in the numbers based on what it tells you.

What % = goes in the % spot

of 60 = goes in the of spot

is 35 = goes in the is spot

  35          x

--------- = ---------

  60         100

Cross multiply:

60 * x = 60x        35 * 100 = 3500

60x = 3500

Divide by 60 to get x by itself.

3500 / 60 = 58.33

Put the percent sign after it:

58.33%

I hope this helps.

The volume of the rectangular prism is 60 cm3. What is the length of the missing side?
sergejj [24]

Answer:

L=10

Step-by-step explanation:

Haley is incorrect because the volume isn't 360cm^{3} it's 60cm^{3}. I know this because i multiplied the length, width, and height together to get 60.

Ocean waves move in parallel lines toward the shore. The figure shows Sandy Beaches windsurfing across several waves. For this p
Eddi Din [679]

Angle 2 is the same as the given angle of 70 degrees so we can solve for y:

4y-30 = 70

Add 30 to both sides:

4y = 100

Divide both sides by 4:

Y = 25

Angle 1 and angle two are supplementary angles and when added together need to equal 180:

We know angle 2 = 70, so angle 1 must equal 180-70 = 110

2x + 10 = 110

Subtract 10 from both sides:

2x = 100

Divide both sides by 2:

X = 50

The answer is:

X = 50, y = 25
