Answer:

tan C = 1.88

sin C = 0.88

cos C = 0.47

Step-by-step explanation:

Trig ratios:

\sin(\theta)=\dfrac{O}{H} \ \ \ \ \cos(\theta)=\dfrac{A}{H} \ \ \ \ \tan(\theta)=\dfrac{O}{A}

where \theta is the angle, O is the side opposite the angle, A is the side adjacent the angle and H is the hypotenuse of a right triangle.

m∠C = m∠Z

\implies \tan(C)=\tan(Z)=\dfrac{25.5}{13.6}=1.88

\implies \sin(C)=\sin(Z)=\dfrac{25.5}{28.9}=0.88

\implies \cos(C)=\cos(Z)=\dfrac{13.6}{28.9}=0.47

Vsevolod [243]
The greatest amount of money that could be rounded to $105.40 would be $105.44. Any higher, and it would be rounded to $105.50.

Find the product mentally. [(x + 1)(x - 1)]^2 pls help. Be quick if you can =)
BartSMP [9]

Answer:

x^{4} -2 x^{2} +1

Step-by-step explanation:

<u>Step 1</u>:-

Given problem is [(x + 1)(x - 1)]^2

by using formula in side square bracket is

(a+b)(a-b)=(a^{2}-b^{2})

[x^{2} -1]^{2}

<u>Step 2</u>:- again we will use formula

(a-b)^{2} = a^{2} -2 a b+b^{2}

[tex](x^2-1)^{2} = (x^{2}) ^{2} -2 x^{2}  (1)+1^{2}[/tex]

on simplification we get

x^{4}-2 x^{2}  +1

<u>Final answer:-</u>

x^{4}-2 x^{2}  +1
