Question

Write the percentage of angles in the triangle (%) if the angles are in ratio 4:6:8.

Answer 1

The given triangle angle in ratio 4:6:8

let the ratio be x

then angle = 4x

=6x

=8x

we know that sum of angle = 180

$4x + 6x + 8x = 180 \\ 18x = 180 \\ x = \frac{180}{18} \\ x = 10$

than angle 4×10=40

6×10 =60

8×10= 80

percentage of angle A

$\frac{40}{180} \times 100 \%\\ 22 .23\%$

percentage of angle B

$\frac{60}{180} \times 100\% \\ 33.34\%$

percentage of angle C

$\frac{80}{180} \times 100\% \\ 44 .45\%$
