Answer:
3/7
Step-by-step explanation:
?
Answer:
name as AB =CD
angle A=angle D
BC=BC
hence angle ABC is congruent to angle BCD
(by sas congruency)
hence proved
<h3>
Answer: 20</h3>
Explanation:
For any rectangle, the diagonals are the same length.
AC = BD
7x-35 = 3x+45
7x-3x = 45+35
4x = 80
x = 80/4
x = 20
Answer:
4x² + 12x + 18
Step-by-step explanation:
This would be the trinomial.
Notice the tickmark on the angles, those angles are equal to each other.
now, notice the angle at the very top, the large triangle is really sharing it with smaller-inscribed triangle, and therefore is equal on both triangles.
therefore, the larger triangle, is similar with smaller-inscribed triangle by AA.
what the dickens does that mean?
