The answer would be 176, because I first combined the x's(minusing 1/4 on both sides), to get 1/4 x +10=54. then I minuses the 10 from both sides to get 1/4x=44. I then multiplied both sides by the reciprocal of 1/4(which is 4) to get x=176
For 2, they would be:
2. 4
3. 5
4. 0
5. 8
You can print a copy of the graph, stick a pin in the origin, and rotate it 180° to see where the figure ends up.
The origin is the midpoint between each vertex and its image.
Negate every coordinate value, for example,
J(-5, -3) gets rotated to
J'(5, 3).
You are not correct. Here's an explanation as to why: First of all, the triangle is isosceles, since it has two congruent sides that leads to the conclusion of two congruent angles, one opposite each side. This means that all three angle measurements of the triangle are x degrees, x degrees, and 40 degrees. To solve for x, add all three values together and set them equal to 180 degrees, the sum of three angles in any triangle. Your mistake is adding only one x to 40, which isn't inclusive of all three triangles. I hope this helped!
Three hundred forty eight thousand five hundred.
Hope this helps!
