Question

In complementary angles, if one angle is three times of other angle, then find the larger angle. class 9 Mathematics•​

Answer 1

Answer:

largest angle is 45°

Step-by-step explanation:

Larger angle = x

$complimentary \:angle = \: 90 \degree$

$90 \degree = x + y + z$

If one angle three times larger than smaller angle

$90 \degree = 45 \degree + y + z$

Here z is smallest angle

So, z = 45/3

$45 \degree + y + 15 \degree$

$y = 90 - (45 + 15)$

$y = 30 \degree$

$45 \degree + 30 \degree + 15 \degree = complementary \: angle$
