Question

state with reason whether it is possible to have two acute angle whose sum is straight angle and acute angle​

Answer 1

Step-by-step explanation:

Let,

A and B be two acute angles.

Then by definition,

0

∘

<A<90

∘

and

0

∘

<B<90

∘

Adding the two equations, we get

∴0

∘

+0

∘

<A+B<90

∘

+90

∘

⇒0

∘

<A+B<180

∘

...(i)

Therefore,

(a) We can have two acute angles whose sum is an acute angle.

(b) We can have two acute angles whose sum is a right angle.

(c) We can have two acute angles whose sum is an acute angle.

(d) We can have two acute angles whose sum is an obtuse angle.

(e) We can't not have two acute angles whose sum is a straight angle.

(f) We can't have two acute angles whose sum is an reflex angle.

Answer 2

Answer:

see an acute angle is greater than O small than 90 straight angle is 180

Step-by-step explanation:

so 60 ,30 = 90 is a acute angle and straight angle will angle 90 ,90 add =180 is a straight angle
