(20 points!) Delisa is designing a website that will be viewable on both computers and mobile devices, so the website as it is s

een on a mobile device is proportional to the website as it is seen on a computer. The diagonal of Delisa's computer monitor is 21 inches, and the diagonal of Delisa's tablet is 9.7 inches.
If an image is 16 centimeters wide on the website when it's displayed on Delisa's computer, how wide should the image be on the tablet? Round to the nearest tenth of a millimeter, if necessary.

Use Law of Sines or Law of Cosines to solve for the missing parts of each triangle​
ella [17]

Answer:

x = 9.7

Step-by-step explanation:

Given

The attached triangle

Required

Find x

Using law of sine, we have:

\frac{a}{sin A} = \frac{b}{Sin B}

So, we have:

\frac{x}{sin 32} = \frac{18}{Sin 100}

Make x the subject

x = \frac{18 * sin 32}{Sin 100}

x = \frac{18 * 0.5299}{0.9848}

x = 9.685

x = 9.7 -- approximated

PLEASE FOLLOW THE DIRECTIONS AND SHOW YOUR WORK. IM OFFERING 15PTS (Way more than its worth) AND BRAINLIEST ANSWER. PLEASE HELP
Alex
I'll take this challenge since I'm not feeling lazy for once....   x would represent Gavin and y would represent Seiji.  

a.  x+y=425, x-y=25   




b.   I will solve your system using substitution.    
x+y-425, x-y=25  
<span>Step 1: Solve </span>x+y=425 for x
x+y+-y=425+-y (add -y for both sides)
x=-y+425
<span>Step 2: substitute </span>-y+425 for x in x+b=25
x+y=25
<span></span>-y+425-y=25
-2y+425=25 (simplify both sides of the equation)
-2y+425+-425=25+-425 (add -425 to both sides)<span>
</span> -2y=-400
\frac{-2y}{-2} =  \frac{-400}{-2}
y=200
step 3: substitute 200 for y in x=-y+425
x=-y+425
x=-200+425&#10;
x=225
x=225, y= 200




c.   Already answered with the picture that is attached.



d.   Gavin earned 225 dollars while Seiji earned 200 dollars.

Find the measure of the missing angles.
dalvyx [7]

Answer:

b = 53

c = 53

Step-by-step explanation:

Alright so we already know that b and c are going to have the same angle measures. We can find b by subtracting 180 degrees to 127. Why you may ask? Its because when b and 127 are added together its obvious that it creates a straight line (supplementary angle). This means that two angles will sum up to 180 degrees. We can create an easy equation and solve for b.

127 + b = 180

b = 53 and c = 53

Best of Luck!

Four lines are drawn on a coordinate plane to form trapezoid WXYZ. Which statements are true about the lines? Select all that ap
Anastaziya [24]

Given a trapezoid WXYZ. In a trapezoid one pair of opposite sides are parallel .Parallel lines have same slope.Slope of line parallel to x axis is 0.If the line starts at the bottom left and goes towards the top right it has negative slope.

All that is true for Trapezoid WXYZ are:

Line WZ has the same slope as line XY.

Line XW has a lesser slope than line YZ.

Line ZW has the same y-intercept as line WZ.

Line XY has a greater y-intercept
