Marco is writing a coordinate proof involving a right isosceles triangle. marco places his triangle on the coordinate plane such that the base of the triangle lies along the x-axis. what coordinates should he assign to this third vertex of the isosceles triangle? (2a, 2b) (a, b) (b, a) (b, b)

Option B (a,b)

If you look at the peak of the  isosceles Triangle the y-axis coordinate should be b, and for x it should be a, since it is halfway between the a-axis, so a is the x-axis coordinate

Isosceles Triangle:

An Isosceles Triangle has the property of having two equal sides that means if side AC = AB then measure of angle ABC = angle of ABC This also means that segment AC is congruent to segment AB

Cost of 1 hamburger = $1.3

Step-by-step explanation:

Assume;

Cost of 1 hamburger = a

Cost of 1 French fries = b

On first trip

3a + 4b = 7.10eq1

On second trip

2a + b = 3.40eq2

From eq2 x 4

8a + 4b = 13.6eq3

From eq3 - eq1

5a = 6.5

a = 1.3

Cost of 1 hamburger = $1.3
