Formula for trapezoid area is A=b1+b2 x heightx 1/2 so your answer would be 161m squared
Seorang ayah memiliki 2 ekor kambing. Ketika ayah mau meninggal, ia mewasiatkan pada ketiga anak kambing itu. A mendapat 1/2 bagian, B mendapat 1/4 bagian dan C mendapat 1/6 bagian kambing. Kambing itu dibagi dalam keadaan hidup. Bagaimana cara membagi semua kambing sesuai wasiatnya ?
Hi there!
Reflections across the line y = -x always go by the rule (-y, -x). We can use this rule to get our answer here. We are given the aftermath of the reflection coordinates, which are <span>A'(-1, 1), B'(-2, -1), and C'(-1, 0). All we have to do now is switch up the coordinate values and multiply them by -1. Here is the work -
A'(-1, 1) => (1, -1) => x -1 => A(-1, 1)
B'(-2, -1) => (-1, -2) => x -1 => B(1, 2)
C'(-1, 0) => (0, -1) => x -1 => C(0, 1)
Therefore, the coordinates of Triangle ABC are A(-1, 1); B(1, 2); C(0,1). Hope this helped and have a phenomenal day!</span>
