Answer 1

Answer:

$\bf{\red{Question}}$

The angles of a triangle are in the ratio 1:2:3 find the angles

$\bf{\red{Answer}}$

Let's consider Angles of traingle 1x , 2x, 3x

We know, Sum of all angles of traingle is 180°

$\begin{gathered}:\implies\sf{ 1x + 2x + 3x = 180°}\\ \\ \\ :\implies\sf{ 6x = 180°}\\ \\ \\ :\implies\sf{ x =}\dfrac{ 180}{6}\\ \\ \\ :\implies\sf{x = 30}\end{gathered}$

$\sf Now\:we \: got \: value \: of \: x \: that \: is \: 30 \bf$

Let's find angles :-

• 1x = 1 × 30.= 30
• 2x = 2×30= 60
• 3x = 3×30 = 90

Therefore, Angles of traingle are 30,60,90 Respectively ! :)

Answer 2

Answer:

The angles of a triangle are in the ratio 1:2:3 find the angles

\bf{\red{Answer}}Answer

Let's consider Angles of traingle 1x , 2x, 3x

We know, Sum of all angles of traingle is 180°

\begin{gathered}\begin{gathered}:\implies\sf{ 1x + 2x + 3x = 180°}\\ \\ \\ :\implies\sf{ 6x = 180°}\\ \\ \\ :\implies\sf{ x =}\dfrac{ 180}{6}\\ \\ \\ :\implies\sf{x = 30}\end{gathered}\end{gathered}

:⟹1x+2x+3x=180°

:⟹6x=180°

:⟹x=

6

180

:⟹x=30

\sf Now\:we \: got \: value \: of \: x \: that \: is \: 30 \bfNowwegotvalueofxthatis30

Let's find angles :-

1x = 1 × 30.= 30

2x = 2×30= 60

3x = 3×30 = 90

Therefore, Angles of traingle are 30,60,90 Respectively ! :)
