Question

If the 1 angle of a triangle is 90° what is the value of other 2 angles?

Answer 1

Answer:

As we know that

A triangle has 3 sides and 3 angle

and sum of all angles are 180°

Now,

let the angle be x

1x and 2x

\begin{gathered}1x + 2x + 90 = 180 \\ 3x + 90 = 180 \\ 3x = 180 - 90 \\ x = \frac{90}{3} \\ x = 30\end{gathered}

1x+2x+90=180

3x+90=180

3x=180−90

x=

3

90

x=30

Put the value of x

\begin{gathered}1x = 1 \times 30 = 30 \\ \\ 2x = 2 \times 30 = 60\end{gathered}

1x=1×30=30

2x=2×30=60

So, the angles of triangle are 90° , 60° , 30° .
