Question

If all the angles of the traingle are in ratio of 2:3:5. then find out measurement of all the angles. Identify the type of traingle.​

Answer 1

Answer:

2x=36

3x=54

5x=90

Step-by-step explanation:

hello mate

so, let the angle be 2x,3x,5x

so 2x+3x+5x =180°

10x=180°

x=18°

2x=18×2=36

3x=18×3=54

5x=18×5=90°

hope it helps

Answer 2

Given : The angles of Triangle are in ratio 2:3:5 .

Need To Find : Measures of all angles of Triangle.

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

❍ Let's Consider measure of all three angles of Triangle be 2x , 3x & 5x .

$\frak{\underline { \dag As \: We \:Know \:that \:,}}$

• $\underline {\boxed {\sf{ \star The \:sum\:of \:all\:angles \:of\:Triangle \:is \:180\degree}}}$

Or ,

• $\underline {\boxed {\sf{ \star \angle A + \angle B + \angle C =\:180\degree}}}$

Where ,

• $\angle A , \angle B , \:and\: \angle C$ are the all three angles of Quadrilateral.

⠀⠀⠀⠀⠀⠀$\underline {\bf{\star\:Now \: By \: Substituting \: the \: Given \: Values \::}}$

⠀⠀⠀⠀⠀⠀$:\implies \tt{ 2x + 3x + 5x =\:180\degree}$

⠀⠀⠀⠀⠀⠀$:\implies \tt{ 5x + 5x =\:180\degree}$

⠀⠀⠀⠀⠀⠀$:\implies \tt{ 10x =\:180\degree}$

⠀⠀⠀⠀⠀⠀$:\implies \tt{ x =\:\dfrac{\cancel {180}}{\cancel {10}}}$

⠀⠀⠀⠀⠀$\underline {\boxed{\pink{ \mathrm {  x = 18\:\degree}}}}\:\bf{\bigstar}$

Therefore,

• First Angle of Triangle is 2x = 2 × 18 = 36⁰

• Second angle of Triangle is 3x = 3 × 18 = 54⁰

• Third angle of Triangle is 5x = 5 × 18 = 90⁰

Therefore,

⠀⠀⠀⠀⠀$\therefore {\underline{ \mathrm { Hence,\: Measure \:of\:all\:three \:angles \:of\:Triangle \:are\:36\degree, \:54\degree ,\: \:and\:90\degree \: }}}$

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

C L A S S I F I C A T I O N⠀:

• As , We can see that the one angle of Given Triangle is 90⁰

Then ,

• The Given Triangle is known as Right Angled Triangle .
