Given, one angle = 48°, second angle = 90°

We know that,

Sum of all the angles = 180°
=> 48° + 90° + third angle = 180°
=> third angle = 180° - 138° = 42°

Answer 2

Answer:

The second acute angle is 42°

Step-by-step explanation:

As it is given that it is a right angled triangle

Then a right angled triangle is one which have one of its angle equal to 90 °

Now

One of the acute angle = 48°

Let other acute angle be = x

Now we have to find the value of x = ?

According to basic geometry we know that

Sum of all angles of a triangle = 180°

AS we have two angles given and one is we have to find

So putting in the equation we get

sum of all angles = 180°

Putting values

90 ° + 48° + x = 180 °

138° + x = 180°

Subtracting 138 from both sides

138° + x -138° =180° - 138°

it becomes

x = 42°

So the second acute angle is 42°
