The measure of one of the acute angles in a right triangle is given. find the measure of the other acute angle

1 answer:

5 0

The sum of angles in a triangle is 180 degrees. In a right angle triangle one angle will be 90 degrees. And if one of the acute angles is already know then just minus 90 degrees and the known acute angle from 180 degrees to find the other acute angle.

180-90-known acute angle = unknown acute angle

The Factorization of 121b⁴ − 49 is (11b^2 + 7)(11b^2 - 7).

The equation 121b⁴ − 49

To find the Factorization of 121b⁴ − 49.

<h3>What is the factor of a^2-b^2?</h3>

The factor of a^2-b^2 is (a+b)(a-b)

We have write the given equation in the form of a^2-b^2

$= 121b^4 - 49\\= (11b^2)^2 - 7^2\\= (11b^2 + 7)(11b^2 - 7)$
