Consider a triangle with angles 30o-60o-90o, with hypotenuse of length 2. Calculate the lengths of the other 2 sides and store t

kumpel [21]

Answer:

1.00 and 1.73

Step-by-step explanation:

1) Calculating the 1st and the 2nd leg using trigonometric function sine:

$sin (30^{0})=\frac{c}{2}\Rightarrow \frac{1}{2}=\frac{c}{2}\Rightarrow 2*\frac{1}{2}=2*\frac{c}{2}\Rightarrow c=1\\sin(60^0)=\frac{b}{2}\Rightarrow \frac{\sqrt{3}}{2}=\frac{b}{2}\Rightarrow b=\sqrt{3}\Rightarrow\: b\approx \:1.73$

Once one leg is found there is another way to find the other leg, using Pythagorean Theorem too.

$a^{2}=b^{2}+c^{2}\Rightarrow 2^{2}=b^{2}+1^{2}\Rightarrow 4-1=b^{2}\Rightarrow b=\sqrt{3} b\approx 1.73$

Sides

a hypotenuse: 2.00

b leg: 1.73

c leg: 1.00

A farmer plants corn and wheat on a 180-acre farm. The farmer wants to plant three times as many acres of corn as wheat. Write a

timama [110]

Answer:

x + y = 180

and,

x = 3y

Step-by-step explanation:

Data provided in the question:

Total area of the farm = 180 acre

x represents the acre in which corn is planted

y represents the acre in which wheat is planted

Thus,

Area of corn + Area of wheat = Total area of farm

x + y = 180 ................. (1)

also,

From the statement, farmer wants to plant three times as many acres of corn as wheat

we can conclude

Area of corn = 3 times the area of wheat

x = 3y ................(2)

So, we have system of linear equations that represent the situation as

x + y = 180

and,

x = 3y
