Answer:

55°

Step-by-step explanation:

so,area of a triangle is equal to 180°
which means:
(x-2)° + x° + 72° =180°
take 72° to the other side and it will be negative
(x-2)°+x°=180°-72°=108
x-2+x=108
x+x=110
2x=110
x=55

I hope that helps

prisoha [69]

B and C are both x-intercepts

An x-intercept occurs anywhere that a line or point touches the x-axis while y=0. With these answer choices, B and C are both values that happen on the x-axis, while y is equaling 0.

Solve for x. 4/x−3+2/x^2−9=1/x+3

Levart [38]

Answer:

$x=-\frac{17}{3}$

Step-by-step explanation:

we have

$\frac{4}{x-3}+\frac{2}{x^{2}-9}=\frac{1}{x+3}$

Solve for x

Applying difference of squares in the denominator of the second term in the left side

$\frac{4}{x-3}+\frac{2}{(x+3)(x-3)}=\frac{1}{x+3}$

Multiply both sides by (x+3)(x-3)

$4(x+3)+2=(x-3)$

Apply the distributive property in the left side

$4x+12+2=x-3$

Combine like terms left side

$4x+14=x-3$

Group terms

$4x-x=-3-14$

$3x=-17$

Divide by 3 both sides

$x=-\frac{17}{3}$
