Name the rectangle ABCD,letting the larger side be AB(7cm) and the smaller side be AC(5cm). Draw the two diagonals across the rectangle. Name the point of intersection of the two diagonals (which resembles an X) F. Name the midpoint between the smaller side AC, to be E.
AFC is the acute angle you are looking for, angle AFE is half of that.
So AFE is a right angled triangle and AE is equal to half of 5cm, which is 2.5; FE is equal to half of 7cm, which is 3.5.
Now, taking triangle AFE,
Tan AFE=2.5/3.5
AFE=35.537 degrees
Since the angle AFE is half of the acute angle AFC that you are looking for,
multiply AFE into two
So, 35.537*2
=71.075 degrees
=71.1 degrees (to 1 decimal place)
AFC= 71.1 (ANS)

An angle that measures between 0 and 90 degrees is an acute angle.
It's called an acute angle.An Acute angle.
An acute angle is between 0 and 90 degrees. Angles between 90 and 180 degrees are called obtuse angles.
The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).
Any angular size between 0 and 90 degrees. An OBTUSE angle is one whose size is between 90 & 180 degrees. A REFLEX angle is one whose angle is between 180 & 360 degrees. NB To correct your English grammar . The question should read ' What size is an acute angle'. When the noun following the indefinite article 'a', begins with a vowel 'a,e,i,o,u'. then the indefinite article is 'an'. In this case it is 'an acute', NOT 'a acute'.
The main differences are. A triangle is three sided while a rectangle is four sided. The corners of a triangle can be any angle. All corners of a rectangle must be 90 degrees. This means that the left and right sides are parallel, and the top and bottom sides are parallel.
The difference is: 1) the rectangle has all right angles 2)a parallelogram has acute and obtuse angles but not a rectangle
There are no acute angles in a rectangle which has 4 equal interior right angles
A rectangle has 4 right angles. There are no acute angles.
Yes, a rectangle has no acute angle (i.e. no angle less than 90 degrees).
A rectangle has no acute angles and no obtuse angles. It has 4 right angles.
a rectangle has 4 right angles
An acute angle is less than 90 degrees. Therefore, as a rectangle has 4 right-angles (90 degrees) there are no acute angles.
No, it is not. It has all right angles.
A parallelogram has 2 equal obtuse angles and 2 equal acute angles whereas a rectangle has 4 equal 90 degree angles
