Answer 1

$\mathscr {\orange{\underline{\purple{\underline{Question :-}}}}}$

find the angle 2x and 3x if one angle is 90° of a triangle

$\mathscr{\orange {\underline {\pink{\underline{Answer :-}}}}}$

First angle = 36°

Second angle = 54°

To find:-

All angles of triangle

Solution:-

First angle = 2x

Second angle = 3x

Third angle = 90°

As we know,

Sum of all angles of triangle = 180°

According to question,

$\large{ \tt : \implies \: \: 2x + 3x + 90 \degree = 180 \degree}$

$\large{ \tt : \implies \: \: 5x = 180 \degree - 90 \degree}$

$\large{ \tt : \implies \: \: 5x = 90 \degree}$

$\large{ \tt : \implies \: \: x = \frac{90}{5} }$

$\large{ \tt : \implies \: \: x = 18\degree}$

First angle = 36 °

Second angle = 54°

Hence,

The angles of triangle are 36°,54° and 90°

Answer 2

Answer:

36 degrees or 54 degrees is the answer
