. Allison drew a triangle with 2 congruent sides and 1 obtuse angle. Which terms accurately describe the triangle? Select all that apply.

Answers

Answer 1

Answer:

Answer:

obtuse triangle

isosceles triangle

Step-by-step explanation:

A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

Area of a triangle = 1/2 x base x height

the perimeter of a triangle = sum of the side lengths

An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side.

$\log_2(5x - 2) - \log_2 x - \log_2(x - 1) = 2$
$\log_2 ( (5x - 2)/(x(x-1)) ) = 2$
$\log_2 ( (5x - 2)/(x(x-1)) ) = \log_2 4$
$(5x - 2)/(x(x-1)) = 4$
$5x - 2 = 4x(x - 1)$
$5x - 2 = 4x^2 - 4x$
$0 = 4x^2 - 9x + 2$
$0 = (4x - 1)(x - 2)$
$\implies x = 2 \text{ or } x = (1)/(4)$

By putting one quarter into the equation we can see that it cannot work in any way involving real numbers as $\log_2 ( (1)/(4) - 1)$ would be log of a negative number, so x = 2.
