In triangle abc angle a +angle b =90 then sin a =
Ivan

Answer:

sin(a)=cos(b)

Step-by-step explanation:

we know that

In the triangle abc

if m\angle a+m\angle b=90^o

then

m\angle c=90^o

Because, the sum of the interior angles in a triangle must be equal to 180 degrees

therefore

Triangle abc is a right triangle

see the attached figure to better understand the problem

The sine of angle a is equal to divide the opposite side to angle a by the hypotenuse

so

sin(a)=\frac{x}{z}

The cosine of angle b is equal to divide the adjacent side to angle b by the hypotenuse

so

cos(b)=\frac{x}{z}

therefore

sin(a)=cos(b)

When two angles are complementary, the sine of one angle is equal to the cosine of the other angle and the cosine of one angle is equal to the sine of the other angle

so

sin(a)=cos(b)

cos(a)=sin(b)

Ravi and his wife are each starting a saving plan. Ravi will initially set aside $125 and then add $40.75 every week to the savi
katen-ka-za [31]

Answer:

  T = 125 +116.40N

Step-by-step explanation:

The total savings is the sum of the two plan values:

  T = A + B

  T = (125 +40.75N) +(75.65N) . . . . substitute the given formulas

  T = 125 + (40.75+75.65)N . . . . . . .combine like terms

  T = 125 +116.40N

If f(x)=2−x12 and g(x)=x2−9, what is the domain of g(x)÷f(x)?
Keith_Richards [23]
\bf \begin{cases}&#10;f(x)=2-x^{12}\\&#10;g(x)=x^2-9\\&#10;g(x)\div f(x)=\frac{g(x)}{f(x)}&#10;\end{cases}\implies \cfrac{x^2-9}{2-x^{12}}

now, for a rational expression, the domain, or "values that x can safely take", applies to the denominator NOT becoming 0, because if the denominator is 0, then the rational turns to undefined.

now, what value of "x" makes this denominator turn to 0, let's check by setting it to 0 then.

\bf 2-x^{12}=0\implies 2=x^{12}\implies \pm\sqrt[12]{2}=x\\\\&#10;-------------------------------\\\\&#10;\cfrac{x^2-9}{2-x^{12}}\qquad \boxed{x=\pm \sqrt[12]{2}}\qquad \cfrac{x^2-9}{2-(\pm\sqrt[12]{2})^{12}}\implies \cfrac{x^2-9}{2-\boxed{2}}\implies \stackrel{und efined}{\cfrac{x^2-9}{0}}

so, the domain is all real numbers EXCEPT that one.
