Answer 2

Given :

Measure of the two complementary angles =2x and 7x

To find :

the value of x=?

Solution :

We know that , sum of the two complementary angles =90 degree.

$\bf\large{\underline{\color{red} According \: to \: given \: condition :}}$

$\\ \implies \large \sf \: 2x + 7x = 90 \degree$

$\implies \large \sf \: 9x = 90 \degree$

$\\ \implies \large \sf \: x = \frac{90\degree}{9} = 10 \degree$

$\implies \large \sf \boxed {\sf{x = 10 \degree}}$

$\\ \mapsto \bf \: 2x = 2 \times 10 \degree \: = 20 \degree$

$\mapsto \bf \: 7x = 7 \times 10 \degree = 70 \degree$

➡ The value of x is 10 degree
