Question

Two adjacent angles are in the ratio 5:3 and they together form an angle 128 degree. find these angles.with procedure and answer.please it is urgent.i will mark the right answer as brainlist

Answer 1

Total is 128 degree
Let 5 be 5x and 3 be 3x
5x+3x=8x
8x=128 degree x=128 divided by 8=16
5 multiplied by 16=80
3 multiplied by 16=48.
So the angles are 80 and 40

Two adjacent angles are in the ratio 5:3 and they together form an angle 128 degree..

$\large\underline \pink{\underline{\bigstar{\textbf{\textsf{\: to \: find\::-}}}}}$

find these angles.

$\large\underline \pink{\underline{\bigstar{\textbf{\textsf{\: solution\::-}}}}}$

sum of two adjacent angles = 128°

And ratio between them = 5:3

let the Frist angle be 5x

and second angle be 3x

now according to question

$\sf \: ⇝ 5x + 3x \: = 128 \degree$

$\sf \: ⇝ 8x = 128 \degree$

$\sf \: ⇝ x = \frac{128}{8}$

$\sf \: ⇝ x = 16 \degree$

Frist angle = 5x = 5 × 16 = 80°

second angle = 3x = 3 × 16 = 48°
