Answer:

Step-by-step explanation:
Given
The attached triangle
Required
Find x
Using law of sine, we have:

So, we have:

Make x the subject



-- approximated
Answer:
Part A:the sum of Side 1 and Side 2= 5x^2+7x-4 Part B all you have to do is the same thing, but subtract the sum of side 1 and 2 from the total. part c they are closed under subtraction.
Step-by-step explanation:
I'll take this challenge since I'm not feeling lazy for once.... x would represent Gavin and y would represent Seiji.
a.
b. I will solve your system using substitution.
<span>Step 1: Solve </span>

for x

(add -y for both sides)

<span>Step 2: substitute </span>

for x in


<span>
</span>


(simplify both sides of the equation)

(add -425 to both sides)<span>
</span>


y=200
step 3: substitute 200 for y in





c. Already answered with the picture that is attached.
d. Gavin earned 225 dollars while Seiji earned 200 dollars.
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!
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
