Question

Find the complementary angles if one angle is 4 times the other angle

Answer 1

let one angle be x .

So the second angle is 4x .

Now since the angles are complementary, So,x + 4x = 90°

5x =90

x = 90/5

x =18°

So x =18 °

4x = 72 °

mark it brainliest plz bro.

happy new year bro.

Answer 2

$\huge\bold\green{Solution:}$

$\sf\color{navy}{Let\: the\:first\: angle\: =x}$

$\sf\color{navy}{then\: the \: other\: angle\: = 4x}$

$\sf\color{navy}{Since \:they\: are\: complementary,}$ $\sf\color{navy}{their \:sum\: = 90}$

$\sf\color{navy}{→ x+ 4x = 90}$

$\sf\color{navy}{→ 5x = 90}$

$\sf\color{navy}{→ x= \frac{90}{5} = 18}$

$\sf\color{navy}{4x = 18 \times 4 = 72}$

$\sf\color{navy}{Hence,}$

$\sf\color{navy}{ The\:angles \:are\: 18^0\: and\: 72^0}$
