A right triangle ABC has complementary angles [tex]\( A \)[/tex] and [tex]\( C \)[/tex].

If [tex]\(\sin(A)=\frac{24}{25}\)[/tex], the value of [tex]\(\cos(C) = \boxed{\frac{24}{25}}\)[/tex].

If [tex]\(\cos(C)=\frac{20}{29}\)[/tex], the value of [tex]\(\sin(A) = \boxed{\frac{20}{29}}\)[/tex].



Answer :

Let's solve the problem step-by-step.

1. We know that in a right triangle, the sum of the two acute angles is [tex]\(90^\circ\)[/tex], making them complementary angles. Angles [tex]\(A\)[/tex] and [tex]\(C\)[/tex] are complementary.

2. In a right triangle, the sine of one of the acute angles is equal to the cosine of the other acute angle, and vice versa. This is because:

[tex]\[ \sin(A) = \cos(C) \quad \text{and} \quad \cos(A) = \sin(C) \][/tex]

3. Given [tex]\(\sin(A) = \frac{24}{25}\)[/tex], since angle A and angle C are complementary, we can infer that:

[tex]\[ \cos(C) = \sin(A) \][/tex]

Therefore,

[tex]\[ \cos(C) = \frac{24}{25} \][/tex]

4. Similarly, given [tex]\(\cos(C) = \frac{20}{29}\)[/tex], we use the complementary property:

[tex]\[ \sin(A) = \cos(C) \][/tex]

Thus,

[tex]\[ \sin(A) = \frac{20}{29} \][/tex]

So the detailed solutions are:

1. If [tex]\(\sin(A) = \frac{24}{25}\)[/tex], the value of [tex]\(\cos(C)\)[/tex] is [tex]\(\frac{24}{25}\)[/tex].
2. If [tex]\(\cos(C) = \frac{20}{29}\)[/tex], the value of [tex]\(\sin(A)\)[/tex] is [tex]\(\frac{20}{29}\)[/tex].

Therefore, filling in the boxes with the correct values, we get:

If [tex]\(\sin (A) = \frac{24}{25}\)[/tex], the value of [tex]\(\cos (C) = \boxed{\frac{24}{25}}\)[/tex]

If [tex]\(\cos (C) = \frac{20}{29}\)[/tex], the value of [tex]\(\sin (A) = \boxed{\frac{20}{29}}\)[/tex]
