Answer:
5/49
Step-by-step explanation:
3/7 x 5/21=15/147=5/49
It can be folded by the up covering the down, it can be folded by the left or the right covering one another, you can even do it diagonally. Any angle of the hexagon covering the one on the opposite side will show reflections symmetry.
Answer:
y= -2/3x+11/3
Step-by-step explanation:
The slope of that equation is 1x or just x 5 is the y intercept
Answer:
Option b. 
Step-by-step explanation:
step 1
In the right triangle ABC
<em>Find the sine of angle CAB</em>
---> the sine of angle CAB is equal to divide the opposite side angle CAB (BC) by the hypotenuse (AC)
substitute
simplify
---->equation A
step 2
In the right triangle BDC
<em>Find the sine of angle CBD</em>
---> the sine of angle CBD is equal to divide the opposite side angle CBD (DC) by the hypotenuse (BC)
substitute
----> equation B
step 3
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem
Triangles ABC and BDC are similar by AA Similarity Theorem
therefore
m∠CBD≅m∠CAB
equate equation A and equation B
solve for DC
step 4
Find the value of AD

substitute the values
