A rectangle is 80 cm long and 20 cm wide. Find to the nearest degree, the acute angle formed at the intersection of the diagonals.

Step 1
We have to find the acute angle
Step 2
20
AB=80
BC=20
1teree, on AABC, tan A fane = BC
AB
20
c 0.25
80
= 1M.0362
Take
a line
pareallel at
ditagenal.
m< BOC=20 =
a to
Acute angle = 28.07 - 28.
