Answer:

11 degrees

Step-by-step explanation:

The bottom triangle has 2 given angle, therefore we know the 3rd angle has to be 29 degrees. Given that the 2 lines are parallel, we know that the upper triangle has 140, 29, and x degrees. 180-140-29=x=11 degrees

Which sum is equal to

Semmy [17]

Answer:

Correct choice is A

Step-by-step explanation:

Note that the denominator $x^2-25=(x-5)(x+5).$ Then rewrite the numerator $x^2+6x-5$ as $x^2+5x+x-5=x(x+5)+(x-5).$

Substitute both expression into the initial expression:

$\dfrac{x^2+6x-5}{x^2-25}=\dfrac{x(x+5)+(x-5)}{(x+5)(x-5)}=\dfrac{x(x+5)}{(x+5)(x-5)}+\dfrac{(x-5)}{(x+5)(x-5)}=\dfrac{x}{x-5}+\dfrac{1}{x+5}.$

A = $\frac{1}{2} b * h$

A = $\frac{1}{2} 15 * 36$

= 15 * 18

Solve this system of linear equations.

yuradex [85]

A) -2, -1
(solve the second equation for x (subtract 2y to the other side, then divide by 2 so x=-y-3) then plug that equation into the x value of the first equation to get y=-1; plug y=-1 into the second equation to get x=-2)
