Answer:

Option A. $(a/2,0)$

Step-by-step explanation:

we know that

If triangle ABC is a right isosceles triangle

then

AB=AC

m<ABC=m<ACB=45°

therefore

The coordinate of point C is $(a,0)$

the x-coordinate of the midpoint M is equal to

$(0+a)/2=a/2$

The coordinates of point M are $(a/2,0)$

We want to place a bench measuring 7.05 feet in the center of a platform that is 40.75 feet long

AnnyKZ [126]

40.75 - 7.05= 33.7
33.7 / 2 = 16.85

Answer:

$m\angle AED=90\degree$

$m\angle DAE=53\degree$

$m\angle BCE= 53\degree$

Step-by-step explanation:

ABCD is a rhombus. AC and BD are its diagonals intersecting at point E.

Diagonals of a rhombus bisects at right angles.

$\therefore m\angle AED=90\degree$

$In\: \triangle AED$

$m\angle DAE=90\degree-m\angle EDA$

$m\angle DAE=90\degree-37\degree$

$m\angle DAE=53\degree$

$\because m\angle BCE= m\angle DAE$

(Alternate angles)

$\therefore m\angle BCE= 53\degree$
