Select all of the names that can be given to the Shape ABCD with the vertices A(3, 2) B(-1, — 2).C(-4, 1). and D(0, 5).

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

the answer is 8/21

hope this

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
