Step-by-step explanation:
Answer:
<em>x=3</em>
Step-by-step explanation:
<u>Angles and Lines</u>
We must recall:
- The sum of the internal angles of a triangle is 180°
- Two linear angles add up to 180°
The image shows a triangle and the extension of its base to form two linear angles.
Note from the triangle, angle R is what it takes to get to 180°:
![m\angle R=180-25x-(57+x)](https://tex.z-dn.net/?f=m%5Cangle%20R%3D180-25x-%2857%2Bx%29)
From the line SQ, angle R what it takes to get to 180°. Thus:
![m\angle R=180-45x](https://tex.z-dn.net/?f=m%5Cangle%20R%3D180-45x)
Equating:
![180-25x-(57+x)=180-45x](https://tex.z-dn.net/?f=180-25x-%2857%2Bx%29%3D180-45x)
Subtracting 180 and simplifying:
![-25x-57-x=-45x](https://tex.z-dn.net/?f=-25x-57-x%3D-45x)
![19x=57](https://tex.z-dn.net/?f=19x%3D57)
Dividing by 19:
x=3
X would be 63, Y would be 27
A straight line is 180 degrees. 180-117=63
To find Y, since we know it is a 90 degree angle do 90-63 which is 27.
Answer:
Find how much she will be paid per mile to make it easier.
.25 * 4 = 1
.90 * 4 = 3.60
Now you know she earns 3.60 per mile, multiply that by 7.
3.60 * 7 = $25.20 total.
Answer:
L2: y-0 = 5/2(x-5)
y = 5/2x-25/2
Step-by-step explanation:
Parallel lines have same slopes.
Line 1, L1: 5x-2y=20 is in standard form Ax+By=C therefore slope m1= -A/B = -5/-2 = 5/2 or you can solve it for y so you will have the equation in slope-intercept form.
5x-2y = 20
-2y = -5x+20
y = (-5/-2)x+20/(-2)
y = (5/2)x-10 hence m1=5/2 and y-intercept is -10
Line 2 , L2: y-y1 = m (x-x1), m=m2=m1=5/2
Point p(5,0) or p(x1,y1) therefore x1=5 , y1=0 and m=5/2
L2: y-0 = 5/2(x-5)
y = 5/2x-25/2
