If one of the acute angles of a right angled triangle is 55 , calculate the remaining angle

lions [1.4K]

Answer:

35 degrees

Step-by-step explanation:

To start off, the term "acute angle" means less than 90 degrees. In this case, the acute angle is 55 degrees.

The type of triangle mentioned in the question is a right-angled triangle, meaning it has a right triangle (90 degrees) along 2 other triangles. A triangle is generally 180 degrees. So now that we know the value of 2 out of 3 angles we do simple math.

Assume the unknown angle is A.

55 + 90 + A = 180

A = 35

Can someone my answers

Answer:

Option 2 is correct that is $\frac{x+2}{x+9}$ and $x\neq-9$ and $x\neq-12$

Step-by-step explanation:

We have been given with the expression $\frac{x^2-10x-24}{x^2-3x-108}$

We will simplify the given expression by factorisation we will get $\frac{x^2-12x+2x-24}{x^2-12x+9x-108}$

Taking x as common from first two terms in numerator and 2 from last two terms in numerator

Similarly, take x common from first two terms and 9 from last two terms in denominator we will get

$\frac{x(x-12)+2(x-12)}{x(x-12)+9(x-12)}$

After arranging the terms we will get $\frac{(x+2)(x-12)}{(x+9)(x-12)}$

Taking out the common factor which is (x-12) from numerator and denominator it will get cancelled we will get

$\frac{(x+2)}{(x+9)}$

Hence, Option 2 is correct that is $\frac{x+2}{x+9}$ and $x\neq-9$ and $x\neq-12$
