. Calcula las razones trigonométricas (Sen, Cos y Tan) de los ángulos agudos de los triángulos rectángulos ABC, tales que:

a. A=90º, b = 15 cm y c=20 cm

b. B=90º, b = 16 cm y c=4 cm

c. C=90º, b = 18 cm y c=12 cm

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
