Answer:

DE = 39.64840676

CE = 35.3269891

Step-by-step explanation:

SOH CAH TOA

Thus,

sin(27) = 18/DE

tan(27) = 18/CE

DE = 39.64840676

CE = 35.3269891

Stolb23 [73]

Answer:

Approximatley 5.8 units.

Step-by-step explanation:

We are given two angles, ∠S and ∠T, and the side opposite to ∠T. We need to find the unknown side opposite to ∠S. Therefore, we can use the Law of Sines. The Law of Sines states that:

$\frac{\sin(A)}{a}=\frac{\sin(B)}{b} =\frac{\sin(C)}{c}$

Replacing them with the respective variables, we have:

$\frac{\sin(S)}{s} =\frac{\sin(T)}{t} =\frac{\sin(R)}{r}$

Plug in what we know. 20° for ∠S, 17° for ∠T, and 5 for <em>t</em>. Ignore the third term:

$\frac{\sin(20)}{s}=\frac{\\sin(17)}{5}$

Solve for <em>s</em>, the unknown side. Cross multiply:

$\frac{\sin(20)}{s}=\frac{\sin(17)}{5}\\5\sin(20)=s\sin(17)\\s=\frac{5\sin(20)}{\sin(17)} \\s\approx5.8491\approx5.8$

What is the form of the Pythagorean triple generator?

stepladder [879]

Answer:(x^2+y^2)^2=(x^2+y^2)(x^2+y^2)

Step-by-step explanation:

We can rewrite left side into right side form

(x^2+y^2)^2=(x^2+y^2)(x^2+y^2)

we can expand it

(x^2+y^2)^2=x^4+x^2y^2+x^2y^2+y^4

(x^2+y^2)^2=x^4+y^4+2x^2y^2

we can add and subtract 2x^2y^2

(x^2+y^2)^2=x^4+y^4+2x^2y^2+2x^2y^2-2x^2y^2

(x^2+y^2)^2=x^4-2x^2y^2+y^4+2x^2y^2+2x^2y^2

(x^2+y^2)^2=x^4-2x^2y^2+y^4+4x^2y^2

(x^2+y^2)^2=x^4-2x^2y^2+y^4+(2xy)^2

(x^2+y^2)^2=(x^2-y^2)^2+(2xy)^2

Gwar [14]

Answer:

4. Z ≈ 46.1°

5. T ≈ 45.2°

6. F ≈ 15.0°

Step-by-step explanation:

We need to use the Law of Sines, which states that for a triangle with legnths a, b, and c and angles A, B, and C:

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Here, we can say that ZY = a = 30, X = A = 110, XY = b = 23, and Z = B. Plug these in to find Z:

$\frac{a}{sinA} =\frac{b}{sinB}$

$\frac{30}{sin(110)} =\frac{23}{sinZ}$

Solve for Z:

Z ≈ 46.1°

Use the Law of Sines as above.

$\frac{a}{sinA} =\frac{b}{sinB}$

$\frac{26}{sin(76)} =\frac{19}{sinT}$

Solve for T:

T ≈ 45.2°

Again, use the Law of Sines as before.

$\frac{a}{sinA} =\frac{b}{sinB}$

$\frac{29}{sin(137)} =\frac{11}{sinF}$

Solve for F:

F ≈ 15.0°
