Answer:

x = 9

Step-by-step explanation:

The triangle given is an isosceles triangle because it has two equal sides. By implication, the two base angles that are opposite the two equal sides are equal to each other.

Therefore,

80° + 2(m<2) = 180° (sum of triangle theorem)

80 + 2(5x + 5) = 180

80 + 10x + 10 = 180

Add like terms

90 + 10x = 180

90 + 10x - 90 = 180 - 90 (substraction property of equality)

10x = 90

10x/10 = 90/10 (division property of equality)

x = 9

What is this problem simplified

Svetlanka [38]

$\frac{x^2 - 5x-6}{x^2 - 36}$

You can begin to simplify this by factoring both the numerator and denominator:

$\frac{x^2 - 5x-6}{x^2 - 36} = \frac{(x-6)(x+1)}{(x-6)(x+6)}$

Next, cancel out any common factors in both the numerator and denominator:

$\frac{(x-6)(x+1)}{(x-6)(x+6)} = \frac{x+1}{x+6}$

Your answer would be $\frac{x+1}{x+6}$ .
