![x=45](https://tex.z-dn.net/?f=x%3D45)
Step-by-step explanation:
The angle sum of a pentagon is 540°
Using this and the angles we know, we can create an equation.
![90+148+112+x+3x+10=540 \\ \\ 360+4x=540 \\ \\ 4x=180 \\ \\ x=45](https://tex.z-dn.net/?f=90%2B148%2B112%2Bx%2B3x%2B10%3D540%20%5C%5C%20%5C%5C%20360%2B4x%3D540%20%5C%5C%20%5C%5C%204x%3D180%20%5C%5C%20%5C%5C%20x%3D45)
Answer:
$5700 - $5500= $200
Explanation:
The total installments: 24 ($175) = $4200
The hire purchase price: $1500 + $4200 = $5700
The amount saved by paying cash: $5700 - $5500= $200
The standard equation for a parabola that opens upward parallel to the y-axis is x2=4ay, where a = distance from the vertex to focus. Vertex is at origin(0,0)
4a=2
a=2/4
a=1/2 or 0.5
the coordinate of the focus is (0, 1/2)
the equation of the directrix is y=-1/2
Answer:
$5.00
Step-by-step explanation:
10 × 50/100
Discount = 10 x 0.5
You save = $5.00
