Question

two adjacent angels are in the ratio 5:3 and they together from an angle of 128°, find the angles

​

Answer 1

Answer:

let the adjacent angles be c, then

5x+3x=128

8x=128

x=128/8

x=16

5x=16×5=80

3x=3×16=48

Answer 2

Let the two adjacent angles be x.

$5x + 3x = 128$

$8x = 128$

$x = \frac{128}{8}$

$x = 16$

5x = 5 × 16

5x = 5 × 16 = 80°

5x = 5 × 16 = 80°3x = 3 × 16

5x = 5 × 16 = 80°3x = 3 × 16 = 48°

5x = 5 × 16 = 80°3x = 3 × 16 = 48°The two angles are 80° and 48°.
