We'll just give the sides a variable, the <span>hypotenuse is A, the height is B and the bottom length is C
A = 21
C = 15
This means the B = is </span>14.696938456699069 which is rounded to 15. But, this doesn't matter.
As long as we know the hypotenuse and one side we can find out that x is equal to about 45.584691402807024, round this to 46.
46 degrees is the answer.

Problem

Tanzania [10]

Answer:

$(x^{2} + 2)(x^{2} + 2)\\x^{4} + 2x^{2} + 2x^{2} + 4\\= x^{4} + 4x^{2} + 4\\$

$(x +1)(x + 1)(x^{2} -2x +3) = (x + 1)^{2} (x^{2} -2x +3)$

At the pie eating contest, Max ate 2⁄5 of a pie and Jen ate 6⁄8 of a pie. How many pies did they eat all together?

Brums [2.3K]

I think you have to find a common multiple for the denominators 5 and 8 which would be 40. so it would be 6/40 and 2/40. then I think, you would add or multiple, depending on the situation, 6 and 2

For what values of x will the function f(x) = 3x² + 13x - 10 equal zero?

Oduvanchick [21]

Answer:

x = - 5 , x = $\frac{2}{3}$

Step-by-step explanation:

the values of x that make f(x) zero are the zeros

to find the zeros let f(x) = 0 , that is

3x² + 13x - 10 = 0

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × - 10 = - 30 and sum = + 13

the factors are + 15 and - 2

use these factors to split the x- term

3x² + 15x - 2x - 10 = 0 ( factor the first/second and third/fourth terms )

3x(x + 5) - 2(x + 5) = 0 ← factor out (x + 5) from each term

(x + 5)(3x - 2) = 0

equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

3x - 2 = 0 ⇒ 3x = 2 ⇒ x = $\frac{2}{3}$
