Answer:
5x^2-3x-8
Step-by-step explanation:
So you will want this to be simplified.
expanding brackets is a great way of doing this
one you have expanded all brackets u get the answer above
:)
x-60 is the length. Multiply you get x2-110x=3000 this is a quadratic equation.
Lets remember the property "alternative-interior angles" when we have parallels lines:
Given two paralles lines, the following is true:
In our question, we have:
We know that the angles J + P + K=180
So, the triangles have all the angles the same, so they are similar by angle-angle-angle, and they have one side congruent, AC=CD, so the triangles are congruents.
