In right triangle ABC, m angle C equals 90 degree. If sin A equals 24 over 25, which function also equals 24 over 25?

Free_Kalibri [48]

Answer:

cos B

Step-by-step explanation:

Let us take a look at angle B

The side adjacent angle B is 24 while the hypotenuse (the side facing the right angle) is 25

The relationship between the adjacent and the hypotenuse can be mapped our using the cosine

So, the cosine is the ratio between the adjacent and the hypotenuse

Hence, cos B = 24/25

use the fact that 10^3 = 2^10 to mentally find a vaule of n for which 2^n > 10^50 & 10^n > 2^300

Rudiy27

$2^n>10^{50}=10^{3\cdot16+2}=10^2(10^3)^{16}=10^2(2^{10})^{16}=5^22^{162}$
$2^{n-162}>25$

The least power of 2 that exceeds 25 is $2^5=32$ , so we have

$2^{n-162}=2^N>25\implies N=5\implies n-162=5\implies n=167$

- - -

$10^n>2^{300}=(2^{10})^{30}=(10^3)^{30}=10^{90}$

The least integer $n$ that satisfies this inequality would clearly be $n=91$ .
