Question

One of the acute angles of a right-angled triangle is 42°. Find the other acute angle​

Answer 1

A Right angle has a 90° And 2 acute angles.

Let,the other acute angle be x.

One of the acute angle is 42°.

90°+42°+ x =180°

132°+ x =180°

x =180°-132°

x =48°

Therefore,the other acute angle is 48°.

Answer 2

Answer:

Question :

One of the acute angles of a right-angled triangle is 42°. Find the other acute angle.

To find :

• We need to find the other acute angle.

Answer :

We all know that ,

• Sum of 3 angles in a triangle is 180°.

• A right angle has 90°.

Given :

Acute angles :

• 90° ( Right Angled triangle )

• 42°

Let the other angle be x.

Now,

$90°+42°+ x = 180° \\ \\ 132°+x=180° \\ \\ x= 180° - 132° \\ \\ x = 48°$

Therefore, the other angle is 48°.

Step by step procedure :

• Firstly , add all angles.

• Then , simplify them and we get the x value.

• Now , the answer is found.

More to know :

• A right angled triangle has 2 acute angles.
