completa con las razones trigonométricas de cada triángulo rectángulo dado y encuentra el lado faltante aplicando el teorema de

Rus_ich [418]

primero vamos a calcular el lado faltante usando el teorema de pitagoras para poder obtener el lado faltante a

$a=\sqrt[]{hipotenusa^2-cateto^2}$ $a=\sqrt[]{100^2-85^2}=52.68$

a=52.68 m

teniendo el lado faltante podemos calcular las razones trigonometricas

$\sin (55)=\frac{85}{100}=0.85$ $\cos (55)=\frac{52.68}{100}=0.52$ $\tan (55)=\frac{85}{52.68}=1.61$

$\csc (55)=\frac{100}{85}=1.17$ $\sec (55)=\frac{100}{52.68}=1.89$ $\cot (55)=\frac{52.68}{85}=0.61$

Write in descending powers of “x” 6x^4+15x^3y2+3x^2y^3

Wewaii [24]

(6x^4) + (15x^3)(y^2) + (3x^2)(y^3) is your answer

As we are looking at descending powers of x. Look at the powers of the x. In the first one (6x^4), the power is 4, and 4 is greater than the other numbers given (3 & 2). Therefore, the order given above is correct.

hope this helps

BabaBlast [244]

100+30=130
100+40=140

online price is 130% or original
superstore price is 140% or original
the difference bewteen them is 140-130=10% of the original price

A. 1.3 times 160=208=online
1.4 times 160=224=superstore

B. difference is 224-208=16=10% of 160
it is 10% of the original price

A. online=$208
superstore=$224

B. $16, this is 10% of the original price
