Question

find two complementary angle which are in the ratio 5:4​

Answer 1

Answer:

Complementary angles so sum = 90

5x+4x= 90

9x=90

x=10

5x= 5[10]

50

4x=4[10]

40

Therefore , angles are 50 and 40

Step-by-step explanation:

Answer 2

$Sum \: of \: two \: Supplementary \: \\ \: angle \: is \: 90°$

$5x + 4x = 90°$

$9x = 90°$

$x = \frac{90}{9}$

$x = 10°$

$5x = 5x \times 10$

$= 50°$

$4x = 4 \times 10$

$= 40°$

$Sum \: of \: two \: Supplementary \: \\ \: angle \: are \: \: 50° and \: 40°$
