The ratio of measure of the angle of a triangle is 3: 8: 9. find the measure of each angle.

Let the unknown measure of angle be =x=x

Ratio of angles =3:8:9=3:8:9

3x+8x+9x=20x3x+8x+9x=20x

Angles in a triangle add to 180∘180∘.

20x=18020x=180

x=18020=9x=18020=9

Therefore measure of largest angle is;

9x=9∗9=819x=9∗9=81

Measure of the largest angle =81∘=81∘

Step-by-step explanation:

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
